Formula 1 supremo Bernie Ecclestone believes crowds will flock to watch motor racing if it were hosted at London’s 2012 Olympic stadium.One bid for the stadium, once the Olympics ends, is for motor racing. The London Legacy Development Corporation will decide its use. SOCCER TEAM FAVOURITESOther bidders are Leyton Orient Football Club, UCFB College of Football Business and Premier League team West Ham United which is said to be the favourite choice of tenant.The bid for motor racing is involved with a little-known company acting in association with F1. Ecclestone denies any involvement. The 81-year old has voiced his interest in hosting a race in London and a recent visit to the Olympic Park, to watch some sports, might have been a chance to asses whether motor racing would be successful at the site.STILL LOOKING"It's surprising how many people have come out, it's good. I'm sure we'd get big crowds," Ecclestone said. "It depends on the circuit, at the moment we are just looking at that. Somebody is looking about going into the centre of the arena and out again, so whether that is going happen or not, we'll have a look and see."The motor racing bid was made in association with a company called Intelligent Transport Services, the London Legacy Development Corporation said. Ecclestone has long backed a street race in English capital, although money, political and environmental concerns have so far proved impossible obstacles. "We looked before about something more in central London, so we'll see what happens. Let's get this out the way, and then we'll have a look at it," he said.
