I usually hate defending e-vehicles but you'd need to be going pretty fast to basically spear the battery box on one of these and puncture a cell to cause thermal runaway. Most motorcycle accidents tend to rip the fork off and send the bike and rider flying, but don't tear apart the frame and engine area aside from farings and junk.

Teslas weigh 100x more and no matter how much I hate to defend Tesla, it takes a big hit for them to light on fire.
