Will a Braking System Increase the Hitch Rating When Flat Towing?

Question:

wouldnt a flat tow bar setup towing a car with a braking system increase the tow hitch capacity as much or more than a weight distribution system does when installed for pulling a trailer?

A weight distribution system allows a vehicle to tow a heavier trailer as it spreads the tongue weight out among several points as opposed to all the weight sitting on one point. As there is little to no tongue weight when flat towing a vehicle (all 4 wheels on the ground), a tow bar is not supporting the hitch or towed vehicle in any other way but pulling. Most will also have several pivot points which would negate any kind of added support.

The braking system will also not increase the towing capacity as it is only there to take some of the strain off the RV's brakes and keep the towed vehicle from pushing the RV when braking.
