currently, speedboost is just making velocity stronger, therfore making car loose any grip and travel even with sides, but imo
it should be changed that way velocity is strengthened AND velocity vector is slightly rotated towards rotation vector of car(no vectors should not match exactly, or it would get boring), to make turns bit more possible with such crazy velocity.
it would open up possibilities for a very very fast drift and "ride as fast as you can handle" races.
