Boris Johnson was left struggling for an answer as Nick Ferrari challenged him over the cycle superhighway.
Lower Thames Street is being reduced to one lane each way due to the new cycle lanes being built.
And when Nick asked the Mayor how traffic would be eased if a lorry broke down, Mr Johnson was lost for words.
He responded: "My dear Nick, it is beyond the wit of man to move a truck? Are you saying it's impossible to move."
But when Nick asked, how's it's going to get there, the Mayor stuttered: "We're confident from the modelling that we've done..."
Then when pressed further, he said: "I really think this is the kind of defeatism. If we'd have this attitude at D-Day... I mean honestly. We've put a man on the moon and you're saying we can't get a truck off a road.
"It's going to be a wonderful thing for the city. This will be something that will improve the quality of life for people in London."
He then insisted this was much better than another plan put to him, adding: "There was a plan, which I had to can, to close the Embankment altogether and turn it into a beach. So count yourself lucky, mate."
