1: If you crash and ragdoll off a bike or ATV then copies of your tools and weapons are spawned by any of a map's spawn points. Of course, when your character gets back up their stuff is still on their person.

(This does cause some weirdness with the Simple Holster Mod where you'll get back up with completely empty hands until you switch to your holster, weapon, or tool. Although, this is far lesser of an issue than the duplicate weapons and tools being spawned at one of a map's spawnpoints.)

2: The truck has a habit of fishtailing when you hit the normal brakes for even a split second shortly before and during a turn. Switching to low throttle does result in the vehicle being more manageable but not by much because it just allows it to more easily slow down without the need of hitting the brakes.
