I agree with you on this, hence phrasing my comment as a reverse "what-aboutism". Handling of liquid fuels has improved quite a bit to where it typically isn't a problem. Whereas at one time you had cars (I'm thinking of a 60's Mustang) where if it got rear-ended gas from a ruptured tank could slosh into the passenger compartment. This isn't much of an issue with modern car designs. And cars have come along way in the ability to protect the occupants. That same protection measures can be applied to the battery compartment if necessary (steal roll cage, elastic restraint system, air bags). Yes, these things need to be thought about, and yes we do have agencies such as the NTSB and insurance standards that will solve the problem.
