Van de Grint about Verstappens: 'They drove back to test in the rain'

Jos Verstappen has invested heavily in the karting career of his son Max Verstappen, so that he can reach the top of motorsport. Kees van de Grint remembers how that went in the days when Max Verstappen was still in karting.

According to van de Grint, nothing stood in the way of the Verstappens to start testing with karts. "They were crazy," says the former Ferrari tyre expert at the Ziggo Sport F1 Café about father and son Jos and Max.
