As tires rotate, they squirm a little bit. That's because the cords pantograph through the footprint. That little bit of movement is like your hand laid flat on beach sand, then wiggling it - the hand sinks into the sand.

On concrete, there is mostly rubber bits rubbed off, but on asphalt, the stone particles are pushed deeper into the binder. Ever notice ruts in asphalt? The road is moving!

You've already forgotten Dieselgate ?

VW screwing the already unrealistic NEDC test cycle because its cars couldn't meet the test conditions - even at the lower-than-low test standards ?
Let alone during real-life road conditions (where NO diesel comes even close to meeting the pollution standards).

You could get a CNG up and run it on biogas in the Netherlands.
They're indeed light on their tyres, and take realistic tyre sizes rather than black road rollers .

I see that with GasDwarf you practice what you preach. Do you have a thread that describes living with the up! and the fueling infrastructure?

I liked the concept up!s because they were rear engined, but just like with the New Beetle, which went from the Polo to the Golf platform, VW dropped the ball.
