Different effects get through enclosed vehicles

[RosieMcCattail]

Now, there are certain effects that can get to you through walls of a vehicle. Not sure if this is specific to a specific type of enclosing part - windshields, doors, quarterpanels, boards or all of them, or some of them, but some things "go through" the walls - I've noticed three so far:

1. !IMPORTANT! Gasoline zombies that you drive over (and kill) set you on fire;
2. Less importantly, blobs that you drive over split into smaller blobs which may or may not spawn inside your vehicle;
3. Boomers exploding when you drive over them splatter you in goo/bile.

This might not be enough to warrant an actual issue, so I've opened this thread.

P.S. acid damage from shots (corrosive Zs/acid snipers) stopped going through, thanks for patching that earlier in the year at some point.
