F1 on the right track in Vegas after parking lot past

Bernie Ecclestone, the one-time supremo who twice took Formula One to a Caesars Palace parking lot in the 1980s, accepts the sport is finally on the right track the third time around in Las Vegas.

The 93-year-old Briton would still not want to bet on the race's long-term success, however.

Red Bull's dominant triple world champion Max Verstappen and his rivals will be speeding down the famed Strip this Saturday, past the lit-up landmark casinos and hotels, in a night-time spectacular.

Ecclestone told Reuters by telephone from his ranch in Brazil that it was the layout he had always wanted and never got.

"The only problem last time was we couldn’t run on the Strip, which is what I wanted to do," he said. "I wanted to make sure when somebody turned their television on they knew they were in Vegas, not in the desert. They promised me ‘yes, we can do it’.

"The first year we ran in this area which was Caesars Palace car park, or part of it, but it was on the understanding that the following year we’d be able to do what I had in mind. But it never happened because the people in Vegas, all the hotels, couldn’t see that it was going to be any good for them.

"So that’s why we never went back to Vegas (after 1982)."

This time the race will be the third in the United States this season, after stadium-centred Miami and Austin's purpose-built Circuit of the Americas.

The race is set to be a sell-out and Formula One and sponsors are pulling out all the stops and spending big to attract the high-rollers and A-listers.

"I hope it is (a success) but I’m not sure it’s long term," said Ecclestone.

"I think the last thing they are concerned with is the race itself.

"The most likely is there will be as big a crowd as you can get, this time around.
