Towing in reverse works incorrectly

[DalenTalas]

When towing in reverse, the towed vehicle remains in place as the towing vehicle backs away, and closes in with the towing vehicle once the latter starts moving forward.

Steps To Reproduce

1. Spawn two vehicles and a tow cable (reproduced using cube vans).
2. Position the towing vehicle behind the towed vehicle.
3. Connect the vehicles with the tow cable. Attach the tow cable to the front of the rear (towing) vehicle, then to the rear of the front (towed) vehicle.
4. Start the towing vehicle and accelerate in reverse. Observe the towed vehicle remaining in place.
5. Stop the towing vehicle and accelerate it forward. Observe the towed vehicle accelerating towards the towing vehicle.

Expected behavior

Towing force applied to the towed vehicle should be directed according to the towing vehicle's motion relative to the towed vehicle, not based on the towing vehicle's speed value.

Towing is currently crazy AF. If you get yourself 14ish tiles away, and then turn around, you can "tow" the vehicle while driving towards it, and the towed vehicle with make the same relative turns that you do, IE you turn to the left and the towed vehicle will turn to ITS OWN RELATIVE left, which is the opposite direction. This makes no sense from a physics perspective, probably the towing code is full of wonk.
Attaching a tow cable to the rear end of the towed vehicle always results in wackiness as well, since the towing seems to be creating forward movement on the towed vehicle, not actually applying force along the tow cable.
I only ever use towing to move shit vehicles out of my way when there is no other path.
Currently to have any chance of success towing you must a. attach the tow cable to the front end of the towed vehicle. b. attach the tow cable to the rear end of the towing vehicle, and c. move straight forward only, and slowly. Turns are sus, speed is sus.
