What happens if you shift into reverse while driving at high speed?

[PrestonDella]

The consequences of shifting into reverse while driving at high speed are: it can cause damage to the car's transmission and engine, and may also lead to serious traffic accidents, even endangering lives. Since the car is moving at a very high speed on the highway, shifting from drive to reverse can instantly cause significant wear and tear on the transmission, such as breaking the transmission gears. Many modern cars are equipped with onboard computers, especially automatic transmission vehicles. If you attempt to shift into reverse at high speed, the onboard computer will automatically deem it an invalid operation and prevent any damage. However, the situation is more severe with manual transmission vehicles. Since shifting gears is entirely mechanical, attempting to shift from drive to reverse can cause gear grinding. Forcing the shift can result in transmission damage.
