I fly to PHX on a weekly basis and normally use a rental car.
Today I actually took a cab a Sky Harbor and as we were driving I felt like he was going really fast. I looked at the speedometer and I saw that it stopped at 100, but he was actually going over that. I think he was doing 95-110 (driving a minibus!!).
I took a picture of it with my cell phone and I'm trying to figure out how I should have dealt with this. Speeding doesn't bother me, but this was overkill (at least in the US). Should I have told him something, should I call the company or just leave it alone since he was friendly and got me to my destination?
