Look, it's not hard to test the cars negativities.
if you or anyone decide to go about it, here's one example how:
take the rpm 1/4 of the rev range below max torque, flik the weight to the side and step on the trottle (for 1/2second to 1 second) while the weight of the car is still on one side. do this with every gear.
Every car in real world would spin in that situation. However most 3rd party mods survive that situation more or less. some even if you leave the pedal to the metal when doing this.
i dont think it is intentional, but making a sim car you cant test it only like you would test a real car in real life, because the real one is REAL.
to make sure that the sim car resembles the real car you have to test it's negativities aswell.
like i said i dont think it's intentional. most modders just dont do that kind of testing, propably because they never tought about it.
