The ropes need to be attached as if they were two separate ropes acting independently, & then the possible load would only be 1T each if they were both carrying the same tension eg. towing in a straight line.

Imagine a bar with the 2 ropes 1 at each end & the bar pivoting in it's middle where it is attached to the car. Each rope has 1T load but the centre pivot ie. total load, has 2T.

Hooking the rope around a tow hitch or a pulley would still leave one portion of the rope taking all the strain & therefore only 1T total capacity.

Having said that it is the initial pull-away from a standing start that would be the problem, once under-way the load would be much less until '1' a hill or '2' a corner when the load would '1' be higher but shared, or '2' more biased towards one 1 rope than the other.

Been there & done that, as the saying goes.

If it wasn't illegal then a motorway would be the ideal place LOL.
