Also back on point, its the overuse and spamming of free LAV that is my main concern.

It's only going to get with worse with the STD BPOs

Still seeing a lot of use of the word "car" as if this isn't a high-velocity armoured vehicle we're talking about but some standard Honda Civic or something. Let's get one thing clear - LAV's are more comparable to a Humvee, not a "car". And that armour and shield you have? It's nothing like the half-tonne suit that Master Chief wears in Halo.

Now, let's talk some physics. I'll keep it simple. There are a number of forces to consider when taking a hit from a high velocity armoured vehicle, including concussive force, energy transfer, and mass. For those in the know, mass is directly transferably to energy. In fact, for those that know something about how mass works at the subatomic level inside a muon for example, mass is made of energy. So, the energy from the speed of the "car" is not the only energy to consider, but it's mass as well. Now, you are not a heavy guy, and while the shields and armour of your suit may protect you against small arms kinetic impacts and directed energy attacks (to a degree), the LAVs are somewhat more massive than you, and larger than a bullet, so a vehicle of this type is going to be transferring a lot of that energy across a much larger area than a small round travelling at higher speeds might do, which will create a concussive force in your armour that has the potential to not just crush you if the wheels happen to roll over you (which, if the armour's any good, it may actually protect you from direct wheel-crushing, unless it was damaged in the impact, which is probable), but the most likely cause of damage from vehicular impact is going to be that concussive force from the energy transfer that scrambles your internal organs into pulp. In fact, it is not uncommon for victims of vehicular impacts to suffer from ruptured spleens and the like with little to no external visible injury.

So, what have we learned today? That's right. LAVs are not Honda Civics. But in the right circumstances, a Honda Civic could probably kill you too. Like if it was dropped on you by a crane. But that's another physics lesson entirely....
