Bruno Senna believes Paul di Resta should have been penalised for their coming-together in the Italian Grand Prix.
Williams driver Senna was challenging di Resta's Force India for 10th on lap nine when the incident occurred.
Senna attempted to go down the outside into the Roggia chicane, but the cars banged wheels and the Brazilian was forced over the run-off.
"It was pretty clear," said Senna. "I had the front wing of my car next to his car and then of course the tyre under braking and he squeezed me off the track.
"We touched. Fortunately, we didn't launch each other but for me a driver has been banned for a race for doing something similar to that and even [Sebastian] Vettel got a drive-through penalty for squeezing [Fernando] Alonso off the track.
"It's a stewards' decision, so we'll respect it, but I don't think that what Paul did was right. It's racing and sometimes we make errors in judgement but it's up to the stewards to decide."
The officials did not impose any form of penalty. Di Resta went on to finish eighth, while Senna could only manage 10th.
