First of all, no, that's very unlikely: around 8 thousand pedestrians die in the US every year, out of around 40 thousand total deaths in traffic accidents.

But also, even if it is, this doesn't mean we should drive instead of walk to reduce our risk - it means everyone should drive less to reduce risk for everyone.

Everyone was very safe on foot, bikes and transit before there were so many cars. Cars made it dangerous to walk, so now everyone is in cars, which also makes driving more dangerous. Then people buy bigger cars that give them higher chances of survival in a crash at the great expense of everyone else involved, so everyone is buying bigger and bigger cars now.
