You can't just 'activate' the braking system on a car. Do you actually have any idea how brakes work on a car?
Yet again you manage to make yourself sound even more silly.
Of course I do. You would have a motor that basically does the job of the foot pedal which could be remotely activated or by cables from one car to the other.
A bit like those remote control cars they have on 5th gear (the full size ones they use for crashes and stuff) but just for the brake pedal.
Obviously this would be totally ridiculous, but that's why I said if you really could be bothered to do it it'd have to be under 750kg to make it worth it so you didn't need breaks. It's still be better to get a trailer though. And that's why I never actually put it forward as a serious proposition.
It wasn't a "joke" as in to make people laugh. It was just a random thing I said which is relevant and true. I hadn't actually thought about how you would physically do it, but it is a legally allowed.
But thanks for more of the personal attacks, I hope you realise there not having an effect though.
