Monaco traffic 'worst it has been'

Button and fellow McLaren driver Fernando Alonso are to take their complaints to FIA race director Charlie Whiting at the next drivers' briefing ahead of the Canadian Grand Prix.

Both men believe the stewards should have clamped down on what they feel to be blatant acts of blocking.

Assessing the events in practice and in qualifying, Button said: "It feels the worst it has been.

"But then we're going to do it unless there is a penalty, and that's the problem.

"I'm sure at the next race [at the drivers' briefing] it won't only be us that complain about it.

"It has been very bad, and some of it has been because the tyres take so long to warm up.

"People are doing extra laps, more out laps, and it just gets very confusing."

Alonso, in particular, was held up badly at one point in Q1 by Lotus's Romain Grosjean towards the end of a flying lap, only for the stewards to ignore it.

Asked whether the stewards had been lenient with traffic issues this weekend, Alonso said: "I think so, yes.

"The traffic we've had this weekend has been quite bad.

"It seems a little strange there have been no more investigations going on.

"In free practice it was ridiculous. In FP3 there were no rules.

"People were going out of the pit lane, doing a very slow outlap, while you were on a fast lap, and they tried to close the door at every single braking point."
