Romain Grosjean has been left upset by Lewis Hamilton's driving behaviour during Friday practice at the Red Bull Ring after the Haas driver was forced into a spin after the Mercedes driver slipped off track ahead of him.
In FP1 with all drivers testing grip levels on the resurfaced tarmac as well as track limits, Hamilton lost control of the rear of his Mercedes and slipped into a spin which swept him on to the edge of the gravel trap.
Grosjean had been running just behind the defending F1 champion and was forced into avoiding action when Hamilton came on to the track backwards, which also caused Grosjean to spin but the pair avoided contact.
The Haas driver says he will raise the incident with Hamilton in the drivers' briefing tonight but was annoyed at the Mercedes driver's actions.
“I wasn't very happy with Lewis' behaviour on track today,” Grosjean said. “He spun, he didn't put the brakes, he reversed in the middle of the track, and I was coming, so to have avoided I had to spin the car.
“We could have had quite a big crash this morning. It's not something you want on your first run in FP1.
“Then in FP2 again he was doing some qualifying run and he going straight at turn 2, coming back and staying in the middle of the track.”
Despite his concerns Grosjean had a largely trouble-free day and finished the quicker FP1 session 11th with a best time of 1m 09.078s.
