Rear wheel steering Research

https://en.wikipedia.org/wiki/Steering#Rear_wheel_steering

Rear wheel steering more suited for slower vehicles with high maneuverability

• Not good for a racecar that needs to go fast

Rear wheel steering tends to be unstable

• This can kind of bee seen with reversing a car, how slight movements can dramatically alter the path

This source controls the rear wheel using a raspberry pi and a relay, with a locking mechanism to prevent unwanted movement

• A solution like this might prove difficult due to imprecise movements

• If the raspberry pi or the relay fails, you cant steer the car and that’s super dangerous

Some verified mechanical engineer on this forum from 2010 says rear-steering is unsafe for anything over 5mph
