Huh? I’m not American! I'm from one of the countries with the least amount of fatalities (in Europe). Secondly I've been driving long enough and I'm savvy enough not to trust that every other car on the road is mechanically sound, or their drivers have the skills necessary for anything more that a trip to the shopping mall and back.I don't know what backwoods part of the US you got your license in (oh, wait, wasn't it USA where the driving test is just a quick drive around cones in a fenced area?), but at least in Europe, the first thing they teach you during your driving lessons is to adapt to the situation individually, doesn't matter what the sign says.
That said, if someone is standing in the middle of the road or crossing the road on red, what do you do? run them over or crash into them?
Also, if someone ignores your right of way, do you do the same? In countries like Germany and Switzerland, people like you are taken off the road in no time at all...
I’ve driven on many roads, in many parts of the world under some of the harshest conditions. In some of places, road signs are treated as little more than a suggestion and some have none at all - I'm plenty "adaptive" and comfortable with my driving thank you very much.
But just because I’m a decent driver and I am comfortable driving in all conditions regardless of the car or road signage I'm not under some illusion that other drivers are on the same level - most are not (and by the way, Europe is no magical exception). There is still no reason to ignore roadsigns or speed limits when posted - this helps safeguard everyone, regardless of skill level.
