If you want to see the world’s most powerful racing car this weekend it will take you around 40 minutes to get there from Bromley.
If only the car could come to you instead ... it would be able to do the 10-mile journey in less than 40 seconds.
Of course that would never happen – the police would probably frown on a car doing 1,000mph and south-east London’s traffic congestion would stop it getting much over a 100th of its limit.
So if you want to see supersonic racer Bloodhound first-hand you’ll just have to make the trip to Canary Wharf, where it’s on display until tomorrow.
It is hoped the £10 million UK-built car will shatter the world land speed record, which currently stands at 763mph, when it is tested at full speed.
The Bloodhound will undergo 200mph trials next year at Newquay Aerohub in Cornwall before embarking on a series of high-speed runs in a desert venue in South Africa. At full speed the car will cover a mile in just 3.6 seconds.
The car, which has been assembled at Avonmouth, near Bristol, is the result of eight years of research, design and manufacturing involving more than 350 companies and universities.
Members of the public can see the Bloodhound with its two-metre-high tail fin - required for stability at high speed - in place for the first time.
Engineers have partially removed the carbon fibre panels from one side of the vehicle in order to show off the technology inside.
Visitors are also able to look inside the finished cockpit - a huge and complex monocoque crafted from multiple layers of carbon fibre - and see the sophisticated digital dashboard.
Believe it or not, driving a car like Bloodhound isn’t as exciting as you’d think.
Project director Richard Noble said: “Driving a car like that is effectively an everyday experience.
"It's all about complete and utter accuracy and complete focus, and if you are getting some sort of buzz or excitement out of it then you are the wrong man.
"It's a very cold-blooded operation."
