Putting a vehicle in reverse when going high speeds forward does not grind gears?

Sooo there's a big ramp on a map i use and I decided to turn off all the transmission safety settings and try to see what happens when you put a vehicle in reverse while going like 150 mph. Nothing happened though? The gears were fine. Am I missing something?

 

I don't really think you are missing something... are you sure that if you will switch to reverse on high speeds, you will grind gears?

 

maybe i dont understand transmissions but i always grew up thinking if you go into reverse while going forward itd break something

 

i did it with older vehicles such as the T-Series and Miramar

 

Doesn't it have to do with the gearbox assists for manual cars? I know that the clutch assist or gearbox safety assist might prevent the reverse gear from actually engaging, but I swear I've wrecked transmissions and engines that way before by turning it off. If you're in an automatic car, I don't think anything would happen.

 

yeah I tried it with manual transmissions and it still didn't really do anything but skid the drive wheels while blazing down the hill
