Driving home today, I decided to whip out my iPhone 4 to test out the GPS accuracy... It found me very quickly, but the blue dot was on the side of the road I was currently driving on... :/ The dot was not exactly on the road. Is there a problem with my GPS chip?
Got a tip for us?

GPS accuracy in Maps

Probably. Not sure how long. Not too long. Also my compass was acting a little strange too while in the car. Apparently something was causing interference. I had to recalibrate it. The compass direction \ / was very very wide. Wider than I'd ever seen it before.
How can I test to make sure my GPS chip is not damaged. I did drop my iPhone onto soft carpet from about 2 feet. With a case btw. Just worried that I'm now finding issues that were caused by the fall. And fwiw, I have ZERO cosmetic damage from the drop. Externally, you would have no idea it feel. No cracks/scraps/dents/etc.
I think as a result of the drop you are more sensitive to finding flaws, its normal to do that. I wouldnt worry, the gps can sometimes be off like that, especialy in built up areas.

Not uncommon for a GPS device to be off by a little bit sometimes. Also consider that mapping isn't perfect either. Plus your in a vehicle.
If you want to test it, walk outside into your yard (clear view if the sky) and sit tight for a few minutes. It may fluctuate a tiny bit. (one or two meters left... Back again. One or two meters up... then back again)
Almost forgot, there was one of those sunspot plasma thingies a few days ago. That can make radio and sat. stuff act a little weird.

I find gps is working quite accurately. Even navigating at 35mph, the location bubble refreshes every few seconds. I'm quite happy.
GPS is generally accurate to witin a few metres at best for commercial devices. If your position is within that after a while with a clear view of the sky, then there is nothing wrong. Your GPS is fine.
Your compass will not work well in most cars since there is a lot of magnetic interference from the dash and the engine.

This. If you have a good old-fashioned analog compass, try it out in your car. I haven't had one work in a car for many years (luckily they tend to be installed in newer cars along with driver's consoles or nav systems).
