Daniil Kvyat has questioned the need for kerbs and sensors which punish a driver for running wide, when a simple grass border with a gravel trap on the other side would suffice.
The Red Bull driver was one of many to suffer suspension failure in Austria after running over new 'sausage' kerbs aimed at deterring drivers from exceeding track limits.
In Silverstone, drivers had their times deleted when they ran across the white line with all four wheels. This weekend in Hungary, new kerbs have been installed with sensors to alert race control when a driver has gone off.
Kvyat says he "doesn't understand" the need and believes grass and gravel would not only be safer, but better deter them from pushing the limits of the track.
"The kerbs are a joke. The kerbs are absolute bulls**t," he is quoted as saying by Motorsport after practice on Friday. "Just think of any bad word and you can imagine and go there.
"Now we have to trust some new sensors. I don't understand it. We just need to put grass there," he suggested.
"It is losing so much – it should be you go on the grass, you go on the gravel, that is it. But there – drivers push to the limit and the white lines are not enough."
Kvyat suggested old school tracks had the right idea with walls close to the circuit and gravel traps which truly punish a driver, rather than large run-off areas and electronic sensors determining whether or not a lap should count.
"If you go to Zandvoort and you put two wheels off the track, you lose a day because you are in the wall," he added.
"Now you lose your laptime if there is some sensor that said you went so far. We are doing a lot for safety, but some things that we had in the past that are old style, or old fashioned, should be kept. We cannot just paint the track with lines."
