Max Verstappen believes kerbs at the Red Bull Ring are "not designed" for Formula One cars after a number of drivers suffered damage during Friday practice at the Austrian Grand Prix.
The yellow 'baguette' kerbs caused a stir last year when drivers damaged their cars while running wide, most notably Toro Rosso's Daniil Kvyat, who was launched into the air in qualifying after going over the kerbs and suffering rear suspension failure. In the build up to this year's race, the FIA introduced extra spacing between the kerbs by moving them 3.2 metres apart.
Despite the adjustments, drivers continued to hit trouble over the kerbs on Friday, with Haas' Romain Grosjean coming off worse with a puncture.
