They don't use modern cars because there are still plenty of old cars on our roads that have drum brakes, no ABS or even disk brakes - cars such as Land Rover Series vehicles of which there are still a huge number still around - my 90 for example has no ABS and it's disc brakes are not as efficient when wet as a more modern set-up. VOSA et al have to take the worst equipped cars not the best when taking examples, any shorter stopping distance is a bonus. 2018 Mini Countryman Cooper S E All4 PHEV in Melting Silver - it’s whisper quiet in EV and polluter modes

Exactly !! Even the highway code has never been updated since cars had non-servo drum brakes all round, crossply tyres when remoulds were commonplace and suspension which would not look out of place on a rickshaw.

Arrrrrrrrrrrghh Now I'm not going to defend "speed school" BUT I am going to defend the one valid point I learnt

I dont care whether you use the scenario of three identical Trabbants, Supercharged Range Rovers or even F1 cars, if the one in the near side lane only just stops before rear ending the stationary car in front of it, the identical car in the middle lane IS going to hit its resepctive stationary car and the one in the outside lane IS going to hit its corresponding stationary car at 78MPH This has "jack all" to do with breaking distances, Brembo brakes or an anchor out of the rear window to assist breaking the fact is that the distance it takes the car in the near side lane to travel from 70 to 0 the IDENTICAL car in th outside lane would only reduce its speed by 22MPH over the same distance And its that single fact that I found interesting!
Now I'm no speed junkie or politically correct "Tree Hugger" BUT the point is very valid and I cant believe I am typing this whilst trying to watch the footy  2015 L405 SDV8 Autobiography, Indus Silver with Black Pack.

what is the range rover's stopping distance compared to a modern family saloon?

Seems like alot of weight to hold back compared to my golf. 2004 black Vogue TD6

Not as simple as that though. The amount of rubber on the road is proportionally larger.

Coupled with the tech the RR has actually makes it stop rather well. Oh and the rear has discs vs family cars still have drums on rear wtf is that about!?

Don't get me wrong, the RR is a heavy old thing, but if you've ever panic braked and felt the EBA kick in it really is amazing how quickly it stops. 

60-0 Distances in feet

Disco was nearest to RR I could get:

Landrover Discovery V8i 44,9

Alfa Romeo 156 2.4 TD 42,9
Aston Martin Vantage 41,9
BMW M 5 neu 38,6
Fiat Brava 1,6 16v ELX 43,9
Fiat Multipla JTD 105 ELX 42,4
Ford Mondeo 2,5 V6 24 V 44,4
Landrover Freelander 2.0 43.8
Smart 45,4 - This has to be the lightest of all the cars!
Corsa 1,0 12 V 49,5

So basically the bigger the car, generally the wider the tyres as a general rule I think? It's all much of a muchness. 

Maybe I'mm missing the point of the scenario but to me it's flawed from the outset as the crash etc is not down to excessive speed as the scenario could be at any speed:-

Inside lane doing 10MPH does not see car in front until 5" away, middle lane car doing 15MPH hits the car & outside lane car doing 25MPH hits car at 15MPH.....

Money for old rope (I would have thought the trainer / lecturer is thinking when delivering his presentation).

What's more interesting and helpful could be RoSPA / Advanced driving courses. I was sent on a few (in a previous life) and completely changed the way I drive, not directly slowing me down (although age ans sense has done this) but enabling me to read the situation better / more accurately. an easy example is judging position of traffic you're following by time rather than perceived distance.

Oh and before I come across as some sort of christian 15mph driver, in safe situations, I have seen the wrong side of 170MPH on a bike, 150MPH in a car so my point is it would be much more helpful if these courses were not just a 'do gooders' knee jerk reaction to 'we need to do something' and more of a legitimate training / re-education....

SWMBO has just made a sarcastic 'you drive like Miss Daisy's in the back' comment so off to re-educate her....

cheers dan. have not had to brake in anger and hopefully never will. 2004 black Vogue TD6

On a LR experience the guy did a demo drive on road. At 1 point he stood on the brake pedal whilst swerving violently from left to right. The car electronics took over and it stopped in unbelievably short distance. I thought my eyes were going to pop out.

Haven't had the need/ bottle to replicate it in my own and hope I never need to! My Previous RR's!

Bearing in mind the 2010+ will do all the braking down to 18mph for you ...... just try it

Scares the willies out of passengers when you don't react to something pulling out on you hehe

It *will* do 140mph-18mph in a damn short space while flashing alerts up and beeping at you! Land Rover Addict
