The Actros is fitted with EBS, if it is pulling a matching trailer, even with a 20ton load, then I would not suggest you tailgate.
It has the capability of stopping shorter than a car travelling at the same speed. This was demonstrated on a video I watched some time back, sorry, can't remember where.
This is also a reason modern trucks do not have front under spoilers very close to the ground when stationary or moving, as under harsh braking it would simply get broken off.

If you search long and hard you will find technical data testing brakes of trucks and with varied results. If you find someone with recent CPC (certificate of professional competence) they will have hand-outs on the formula's for working it out.(I dont have mine as it was so long ago or I would post it.) Unlike cars that have a simple braking system, Goods veh's with abs/eps air systems are designed so that brake effect increases relative to the load on it. Simply put, if you put more weight on, load sensors increase the ammount of brake effect.
