hotfix:
[+] Fixed misalignings between console command names and actual incode variables (rm_tanksystem convar should work fine now)
[+] added new console command: rm_carsmodule_to_defaults - sets every variable added by this addon to defaults
[+] ragdoll on simfphys/lvs cars now spawns lower (20 hammer units to be precise)
[+] set rm_upvector default value to 0

REWORK UPDATE!
[+] Changed console commands values now keep between game sessions
[+] Updated default command values to make accurate to initial crash speed force
[+] Rewritten applied forces calculations
[+] New console command: rm_upforceratio (default 0.2): Ratio of up force to forward force, so closer to 1 higher you'll fly
[+] Camera keep's at place when you fly off the car (note: simfphys/lvs cars - inherits direction of car, glide - keeps initial camera angle, but works only on motorbikes and quad bikes)
[+] Tank system now works on Glide aircrafts and tanks!
[+] Changed place where ragdoll appears initially on crash: it's right on the seat now (20 hammer units up above for simfphys/lvs cars so if you mind set rm_upvector to 0)
[+] added temporary nocollide between ragdoll and car (200ms to be precise)

[+] Glide \\ Styled's Vehicle Base Support!
Notes: Completely removes built-in fly off feature and conditions for flying off, Tank system doesn't work (you're able to fly off tanks, military enclosed vehicle and aircrafts).
[+] Now every passenger can fly off the vehicle.

[+] Removed error message appearing when getting sit at default gmod seat

[+] Addon works again now.
Commentary on this situation: So simfphys and LVS developer just decided to make a huge API update on their addons well both of the addons are a completely separated ones, so to keep things as they was before, I had to apply patches to both the simfphys cars, and LVS machinery. And thanks to Facepunch for renaming "PhysicsThink" function to "PhysicsUpdate" so addon just couldn't apply the patch right away.
[+] Fixed the issue while in tank (or any highly enclosed car) you didn't received any damage, but straight up die. Now you receive damage, but you won't know it, unless you either die, or leave the vehicle and look at your health.
[+] Remade calculation on taking damage in tanks in a much more spare way. With full health you would die if you fly from these tall houses in gm_construct. that was the starting point from my perspective.

fixed a mistake done with latest update

[+] New console command: rm_pushmultiplier - Initial fly off speed multiplier

Fixed a bug when setting rm_gripforce to zero doesn't disabled this addon
Removed unnesessary debug information that was printing in the console

+Trying to leave the car in move causes player to move the same speed car have.
+Fixed a bug when trying to switch seats or leaving the car while seating in one of those caused player to fly off in one direction at insane speed.
-Players sitting in the car have fully disabled Ragmod, which will break addons that could try to ragdollize players in the cars.
-Trying to press Ragdolize button while in simfphys car don't do the thing anymore.

-fixed LVS Cars compability now it works with any drivable entities based on LVS Framework (I hope so)
-added tank support: on impact instead of flying off the tank you'll receive damage (either receive >100 dmg or don't take dmg at all)
-added multiplayer support: now everyone in the car receive same benefits from impact
