Cars are not the solution to that. Hooligans and irritating people are just a possibility in literally every social environment, they always have been, and they always will be. Answers to that problem are social - it's a bigger problem in America than Japan, for exmaplem.

Answers which involve removing oneself from society (by entering a private car) are not good answers. And when you factor in the externalities, you're just displacing "I'm upset, possibly even unwell due to sleep lost" onto "we replaced 90% of the local natural environment with pavement and paint it with crushed human beings every single day".
