I suspect you'd see fewer people driving if it was 1 in 10

Everybody dies, and I need to get to work/see grandma/go to the grocery. People drove about as much in the 60s, when the per-vehicle mile travel deaths in the US were 5 times what they are today.

I don't. The cohort of people that make risk assessments with regards to routine every-day things and change their plans accordingly is minuscule, and most places around the world do not have an equivalent form of transportation.

Even with minor/un-needed activities people tend to ignore risk. Every cigarette smoker over a long enough period will develop health problems and eventually die faster than they would have otherwise, but it's still a thing; and it doesn't offer the advantage of actually facilitating getting to work on time and feeding your family.
