Yeah, I still remember that when I was in Texas, there were people that stayed in a hotel very close to the HQ of our company - it was just on the other side of a big road (few lanes) - but as Europeans think, they assumed there is a pedestrian crossing, but there was none, there was no sidewalk, nothing.
The only way to get to the other side of the road was using a vehicle - there were few hired shuttles that were driving people from hotel to work and back, quite insane.
A week before I was in SF and public transport there was decent, but the vehicles were like from 1950s in comparison what I'm used to use in my country, e.g. if I wanted the bus to stop I had to pull a wire (yes, a wire!) to notify the busdriver that he/she should stop on the next bus stop.
That's just one of the issues, and the quality of the bus was no where near the current ones we had in Europe.
On the other hand the bus drivers were very friendly and open.
