Totally unrealistic - if a vehicle can't safely slow from 60mph to 20mph in less than 500 metres then either the vehicle or driver shouldn't be on the road! An emergency stop from 60-0mph is 73m according to highway code para.126 (dry conditions, vehicle in good repair) - so achieving 60-50mph in 500m should be quite a comfortable brake!Okay so you have this busy A road traffic flowing in both directions at 50 mph so no chance of a vehicle overtaking if coming up to a slow moving vehicle. Theres a break in the traffic of 1500 mtrs the oncoming car is traveling at 25 mtrs per sec in 10 seconds you have pulled off the lay bye onto the road the car is now 1250 mtrs behind another 10 second you have travelled 25 mtrs the car 250 mtrs so now only 1025 mtrs away. another 10 seconds you have travelled 50 mtrs the car 250 mtrs so now only 825 mtr away another 10 seconds your now at full speed you travel 125 mtrs the car 250 mtrs now only 700 mtrs away another 10 seconds you travel 125 mtrs the car 250 mtrs now only 575 mtrs away final 10 seconds of the first minute you travel 125 mtrs the car 250 mtrs now only 450 mtrs away.
How realistic do you actually think this is. From zero start to flat out 25 mph with typical 10 tonne load in 30 seconds.
