A wallride is a technique where the car intentionally rides along a wall at high speed instead of braking and taking a corner normally. In some situations, this allows for a faster corner exit and can be quicker than a conventional racing line.
However, wallrides are generally slower than using Double Steering.
A wallbounce is a technique where the car briefly bounces off a wall instead of riding along it. This can help achieve a better angle through a corner while maintaining more speed.
With certain cars, wallbounces can be combined with the Double Steering technique for additional speed.
