To much electrics in mod cars, battery isolator would have helped, why did they not disengage the toe car from the tractor.
Assuming you mean "A" frame towing... Some Smart cars are suitable for "A" some aren't. Depends on gearbox. If anyone is thinking of doing this I suggest a little research first. If "Hospital trolley" means a dolly with 2 car wheels on dolly and 2 on the road. These are illegal except for recovery purposes.not sure but believe there’s an issue with towing smart cars have to be done on an ambulance trolley prevents their transmission overheating could be something like that ?
