Increased ban on radio chat to make F1 races harder, Hamilton feels

There will be a stricter enforcement of the regulations around radio messages, requiring each F1 driver to drive his car 'alone and unaided'.

Mercedes boss Toto Wolff believes the rules will make drivers more prone to making mistakes or wrong strategic decisions during a race.

Hamilton said: "It is a big change and whether or not I agree with all the of the implications I think it's definitely going to make it a lot harder.

"We have to memorise a lot more things, there's so many different processes and sequences we have to go through in the car.

"We just have to figure out ways in which we can try to remember them.

"Sometimes you will see stickers in the car or stickers on the steering wheel because there is literally so much."

Hamilton added there are elements of the new rules that he is not in favour of, because they do not directly impact on performance.

"Some of it is of no benefit in terms of improving our pace or anything like that, it's just to keep the car going because it is so technical," he said.

"That's why I say some of it I don't agree with because it's irrelevant to the pace of the car or to the spectators.

"The idea is probably a good thing and you'll see it evolve over the races.

"We're all going to struggle probably in the first race in some way or some form but we've tried to prepare the best way we can."
