Yea - if you can’t keep the car on the track without the limits, it probably shouldn’t be driven. Fair penalty really.
That's a problem for Aston

Increasingly obvious that the Aston has at least as much of a problem with aero and chassis as it does with the engine. The onboards are just dreadful. Newey blaming Honda when he should be looking in the mirror.
Although, to be fair, he was given a pretty impossible task.
