Your gear linkage is offset!! Or you are on a steep down hill
It could be the transmission, it could be some parts under the vehicle that rub only when travelling forward.

Engine idle too high.
Friction
A reversible process is one which can be reversed and causes no changes in the system or surroundings. For a process in equilibrium, the rate of the forward process equals the rate of the reverse process (which can be, but is not necessarily equal to zero).

Both a stuck reverse switch and shorted wiring can be causes for reverse lights to stay on. Under normal circumstances, the reverse lights turn off as soon as the vehicle is shifted out of reverse.
One possibility is a brake caliper that has a broken or missing bolt. Or something has broken inside the front axle.
In a reverse fault the maximum principal stress is horizontal, compression causes reverse (thrust) faults.
