Lewis Hamilton has likened the Miami International Autodrome's chicane at Turns 14 and 15 to a "B&Q car park", adding that the circuit is also considerably bumpier than he had expected.
While the 5.412-kilometre Miami International Autodrome features long straights and sweeping curves, it also tightens considerably between Turns 11 and 16, and its temporary nature makes the track surface less smooth than that of a purpose-built circuit.
Asked how he found the Miami track, Hamilton replied: "Bumpy. It's kind of crazy when you think that people in this day and age should be able to make a flat road relatively easily.
"There were big, big, big bumps and so many places where the track joins up somewhere else, so I don't know if they'll be able to grind that at night and improve it.
"But otherwise, the track's quite nice to drive, except for the chicane, [which] is so tight. It reminds me of being in the B&Q car park when I was six or seven years old, in a go-kart, going in between cars!
"Maybe, in future, they can remove that one and it will improve the track."
Hamilton's thoughts on Miami's bumps echo those of Lando Norris, who added that he feared Sunday's race may turn into a procession due to the amount of discarded rubber that accumulates off the racing line.

Turning up the Miami heat
With temperatures in Miami to top 30 degrees Celsius for the rest of the weekend, the inaugural Miami Grand Prix is set to be one of the hottest of the year, and Hamilton acknowledged the physical challenge this would represent.
"The race is going to be tough, particularly as the tyres were overheating and it's very hot all day," said Hamilton.
"It's a track where I think today I've already lost a couple of kilos, and over the next couple of days, another two tomorrow, and then the race is probably going to be right up there.
"It reminds me a little bit like driving - not as fast - but Malaysia, KL (Kuala Lumpur). Not far off that. KL is still number one in terms of the heat, then Singapore, and now here."
