So are people arguing that they would only buy Conti's because in the contrived circumstances of the programme they stopped "on average" better. What happens when you discover that Bridgestone, Pirelli or Michelin make a tyre that stops better than the Conti in those narrow conditions to you switch to those.
It's all marketing hype, it's what Marketers do, the sell stuff and they use whatever information suits their case no matter how tenuous the evidence, read beyond it and make an informed choice.
For my part I'd like to know what real world conditions would have to exist in order to re-create the test scenario, my guess is it would have to be very heavy rain in order to maintain 1mm of standing water, effectively hydroplane conditions, and frankly if you're still travelling at 70 in heavy rain you're asking for trouble.
How often have you only seen a wrecked lorry strewn across the motorway only within the stopping distance of your vehicle? Probably never nor are you likely to, you'll see it well before, even if you are two car lengths behind one when it starts to lose control it's still moving forward and you can decelerate with it. I've certainly been in that situation once or twice and with a cool head, came to no harm, irrespective of what tyres or car I was in for that matter.
You also should be looking in your rear view and side mirrors regularly to know where cars are around you in the event you need to take evasive action or slam on your brakes, how many folks just blindly look ahead, far too many if you ask me!
Just pick the tyres that meet your driving requirements, some are great in the rain but not as good in the dry, some last longer, others shorter it's always a compromise. But remember all tyres performance will become poorer as the tread depth decreases (surprisingly so at the min legal tread depth), everyone knows that, you can feel the difference immediately when you put new tyres on. So I guess all those folks throwing their hands up in horror about the stopping distance difference change their tyres every month or two because the stopping distance is constanly increasing!
Sounds like it was a "fake" programme purporting to be real investigative journalism!
