Force India's Esteban Ocon took a close look yesterday at the speed bumps placed at Mexico City's track and didn't like what he saw.
In a bid to avoid the track limit transgressions which marred the end of last year's race at the Autodromo Hermanos Rodriguez - and indeed the end of last weekend's controversial race at COTA - the FIA has placed 50 mm-high speed bumps on the left hand part of the track between Turns 1 and 2.
Ocon assessed the bumps during the team's traditional track walk and left with a negative imprssion.
"No one wants to go off, but it is a bit harsh," he said.
"It is dangerous. You are going to launch and I think it's not going to stay like this. I think if someone hits that they will have to make a chassis change."
Ocon also pointed out the fact that a driver running wide would either have to run over the grass or over the bumps to rejoin the track.
"There's no way to rejoin, we can't rejoin the track so we have to cut the grass," he said, underlining the potential risk of chassis damage.
Haas' Romain Grosjean agreed with his countryman's critical observations, and added a few of his own.
"Turn 1, there is a slight issue in that you can’t rejoin the track, you don’t want to go there," he said.
"There is no route bringing you back to the track. That needs to be thought about.
"There’s another tricky one, which is Turn 7. If you go wide there, you have to come back around an orange bit, it’s pretty narrow. But the rest works."
