Invulnerable car bug, again! Here's the usual:
Weird health indicator (a single collision deals absurb amount of damage, but the health overflows around, i think)
Invunerable (duh)
This invulnerability is random, the car just suddenly went from 900 health to like 92000
Invulneraility ends randomly
This was the first time for me to have this bug occur with a passenger
