GTA V glitch

[Claude speed GTA III Fan]

sorry guys if this has been asked before

when i use bulldozer or dump truck and run over a car, it explodes and i die ,but my truck stays fine, why does this happen, it's really annoying, i waited for the patch to fix it, but it's still the same

also my tank will explode after i run over two cars and they explode

in real life cars don't explode when you go over them with a monster truck or a bulldozer !! and this glitch makes the game boring and not funny anymore, beceause all the fun is when u take the dumper and go over cop cars and wreck them, also i noticed that the big truck like packer feels very light and instead of u pushing cars when u hit them, the game will act the opposite, whenu hit a car u get pushed back, also cop cars are heavier, and when they push u with their cars when they are chasing you, they push u my truck offroad

should i reinstall the patch ?
