Right but I don't quarter mile my road car on public roads and risk going to prison. So I don't care what the trap speed is, I just care how it gets to 70mph, how it corners (We have lots of those in Europe), how comfortable it is for me and my family, etc. Frankly unless you go out at like 3am you'll struggle to find anywhere you could quarter mile a car here, plus a lot of roads that might be suitable have speed cameras on them.
So do I want faster than 4.2 seconds then yes, it's why I'm here but not if it compromises the car in a lot of other ways.
There's no such things as a Plaid in the UK. Nothing much is beating a M3P on UK roads and not much actually beats a LR. Sure there's ICE cars that do it with launch control but no one does launch control on the road here. So those say 3.5 second German saloons are probably more like 4.5+ when they accelerate off boost, having to release the auto parking brake, start the engine from stop / start, etc.
