Interesting theory, I would have assumed the exact opposite. People who want to drive fast and take risks will select manual driving because they'll find the autonomous cars too boring.
It's a numbers game. Those people basically don't exist compared to cheapskates who want to drive old cars and people who crash cars driving distracted. It's gonna come down to how many people who want to text and drive or do other sketchy stuff want to make the jump to autonomous cars. Classic car insurance is already stupid cheap just because it implicitly excluded a bunch of risky demographics.
