My method for navigation:

Google/Yahoo Maps + My Printer

Either that, or a good old fashioned map. Of course, I rarely go anywhere I don't know my way around, and if I do, I'm trying to get lost...

Ditto!

I had a sat-nav for about a week.
For the first two days it kept nagging me and we kept fighting:
"in 10mt turn left"... (a few seconds later)..."turn left"...
"I got it the first time, you idiot! If your so smart then you bloody drive!!"

Then I found the "quiet" setting and at that point my only purpose in life was to beat the ETA (by at least 20%) and disagreeing with just about any route recommended.

Now I've also gone back to google maps printouts and good old orienteering.

It seems like an occasionally recurring theme is a reference to some kid's game.
The warm/cold thing would be an example.
Maybe it's nostalgia in general, maybe it's just a juxtaposition of tings that don't usually go together. It works.

HTC 8925 (aka the AT&T Tilt) + Google Maps for Mobiles ( http://www.google.com/gmm )

Here's how it works:

Run Google maps.
Click "Use GPS"
Click "My Location [0]" (if you can't get Sat signal, it will approximate based on the nearest cell tower, which is important for the next step)
Click "Search"

Yada yada. I usually after reviewing the turn by turn directions, I'll hit "My Location" again and just follow the purple line. It does not give active turn by turn, nor does it have voice prompts, nor does it auto re-calculate the route. It is free (as in beer), however, which makes it ultra sexy.

I don't like voice directions, they're a distraction. I prefer to listen to my music, and not have some high and mighty voice tell me I'm driving wrong.

The GPS could just say 'your in the right ball park' or 'your in the correct ZIP/Postcode.'
Some GPS units are quite poor with the directions they give. Can be frustrating.

Which, if written in python, would consist of approximately 3 lines. 4 if you want to keep things neat.

Actually, it's probably possible in just one. Assuming we have our own x and y, our destination x and y, and our heading, and we want it to say RIGHT if we need to steer right more than 45 degrees. Something like

Code: Select all

import math
["STRAIGHT","RIGHT","LEFT"][cmp(int((((math.atan2((dest.y-curr.y),(dest.x-curr.x))-heading)*4/math.pi +4)%8 -4),0)]

Okay, 2 lines. I need to import math... It's probably possible to write a custom arctangent function in that line as well, and I know Pi to more decimal places than a floating point number, but I think you get the picture :)

My GPS is pretty good, unfortunately it cannot help when the one-way streets are randomly altered, and each day a different road is closed just for the hell of it.

Fortunately the random road changes came about after I got to know the neighbourhood well enough to work around them all.

What would be nice for closed road is a button that let's the GPS know you turned off route due to a closed road, and for it to avoid that road for the next 1 mile/5 miles/10 miles or something when it recalculates the route, instead of trying to route you back onto the closed road...

On one trip, using Google maps, I found that Google had given me contradictory instructions: "Take 1st exit at roundabout", immediately followed by: "Take 2nd exit at (the same) roundabout"... It was... odd.

Anyone more knowledgeable about GPS systems want to weigh in on this idea?

The 3D was rather awesome, or at least I thought so.

There should just be GTA-style GPS systems. Your car is at the center of a circle, superimposed on a map with a coloured dot at the edge of the circle to indicate where to go. Works OK in a city; doesn't work so well in wider, more open areas. (Seriously sucks for the open areas of GTA:SA)

Unless it's like my old one, and the ratchet in the pedals jammed. Then it can go both forward and backward.

As for the comic, it would be an interesting project. I suppose if the GPS provided a "distance to" value, you could use that, along with preset cutoff points, or register the temperature.

That's pretty much my method, but with Mapquest.

OK...once or twice Mapquest has steered me wrong. This is why I sometimes take this extra step: If I'm going for a job interview, I'll ask them what their building looks like, and what businesses/landmarks are they next to or very close to, like restaurants, the post office, car dealerships, etc.

*hangs head in shame*

It appears my GPS does have this option in a buried menu, and I just didn't realise it.

I just had a completely independant discussion with a collegue which turned to GPSs and he mentioned it completely unprompted...I checked, and indeed I have it.

Doh!

If i know where something is without knowing the route, I actually do navigate in a way similar to the alt text. No GPS though.

Seeing the title I honestly thought I'd clicked on Hack-a-day (also in my RSS feeds) and mentally preparing for what they might have come up with this time. It was a really odd feeling having to readjust my brain when that wasn't what came up.

I usually use google maps or mogologo on a cell (a boost i415) or if it's a longish trip an e-trex with preprogrammed waypoints. Not the most elegant thing, but I don't drive many places I don't know how to get to. If it's local, I often simply use the e-trex with a single point which isn't that different from this ("you need to go x miles that way ->" without regard for streets and such) but works pretty well.

Voice GPS's suck. End of story.

I like the picture ones, even if they are a distraction from the road. In any case, nothing beats plain old maps! I just like signs, I guess.

I hear a lot of anti-GPS talk here but I want to say, the one I bought in, like 2004 for around $600-$700 has paid for itself many times over in reduction of stress. Now that they're like a couple hundred bucks it's a no brainer.

(Part of that is being in Boston, which is kind of notorious for having odd layouts of unlabled streets.)

It's not perfect; this older model will lose signal a little more easily, especially on really cloudy days or when surrounded by tall buildings or in tunnels. And I declined to upgrade its map so its still caught in this mid-Big Dig world

But it is SO much better than nothing, or what I used before, that one big Arrow atlas, or printouts from Mapquest. It is to changing driving plans what cellphones are to changing plans with other people; an incredibly enabling technology (err, that you shouldn't really engage in while actually driving at the moment, but still.)

The use of "Arrive" as a command -- "tURN rIGHT, tHEN aRRIVE aT dESTINATION" - is a bit weird.

I enjoy thinking of my GPS's personality as a variation of GlaDOS... a bit passive aggresive. "fINE. iGNORE mY aDVICE. sEE iF i cARE."

I use delorme street atlas USA with a topo for backup (also delorme). My palm has the software, but i use that for out of the car navigation (read geocaching). for in the car, i use a laptop. The delorme GPS thing is freaking amazing, if you miss a turn, or know a better way, it doesn't tell you to turn around forever, it says "missed road, 10 seconds to recalculation, press any key to stop" or somesuch. You can disable that, too. Either way having "shortest" "Fastest" routes are nice. It's really good for medium to long trips (on the scale of several hours to several days); it's good for point to point short trips (read geocaching) - but if you're trying to find a house nearby in a dense neighborhood, it's about as useful as a printed map.

The GPS units i have are not standalone, and as such they're very freaking fast. It can do bearing and speed more than once per second (including serial/USB lag!), and once it's powered on it gets accurate bearings really fast.

Highly recommend the package for anyone that can drop a couple hundred on a similar setup. The voice system is pretty nice too, but i never use it. I'm generally with another person in cars, either i or they handle one job.
It's a luxury, it's no excuse for not knowing how to read a map. you can get more lost relying on GPS or even google maps or mapquest than just aimlessly driving towards a city.

Did i mention it integrates with netstumbler nicely?

No, but I think there's some DK listening in my very near future.

As for the GPS asswankery, I only have a handful of experiences with the things and I really don't care for them. They're great if you're in a strange place for the very first time, but after that, I would never use the damned things.

Plus, my ex's family thought that the Australian woman voice was freaking hysterical. That was awful for two reasons: one, the fact that we constantly overshot destinations made it say "Re-cow-cue-leigh-ting..." about once a minute; and two, the internal speaker was either weak or absent, and it used an RF modulator instead. So them being unable to find their way around town cost me the ability to listen to music.

I don't know about y'all, but I for one usually know which direction I'm headed, and not just relative to whatever road I just came off of. So if I ever tell you that I was late to something because I got lost, I'm completely lying my ass off. God, I hope none of my future employers read this forum...

Consider it gotten. Add fake DME and you could probably actually find your destination, although you might have to break out some paper to do some plotting.

"Cheap GPS" is timely for me, I just bought a cheap old used GPS off of eBay. Of course, since it's for aviation, it was still almost $500, but that's about as cheap as it's going to get.

I'm more concerned that the car doesn't appear to have any pedals. I would so definitely buy one of those hot/cold GPS systems though, but wouldn't the effectiveness of that system decrease dramatically with distance from your location since it's not telling you directions but the distance from your target?


You could make it hot or cold depending on your path's similarity to the optimal path?

I also like how the comics are getting more detailed.


Tom-Tom nearly drove me off a cliff once. I wish I was kidding, but I'm not.


Haha, that reminded me of "the office" episode where Michael's GPS made them drive into a lake

What I want to know is how he managed to go from "hot" to "cold" with no "warm" in between.

Well, driving directly past your destination (directly over it, to be more precise) would result in you, having been on the optimal heading with minimal distance to travel, suddenly facing 180 degrees off target with ~40k kilometers to go. That would seem to fulfill most requirements for being cold...

In Florida last December, my father and I were using a GPS to try and find a Pizza Hut. Food is conveniently marked on the map.

Upon arrival, however, we found a cemetery, not a restaurant. Somewhat disconcerting.
