Richard Ingham, who has served as Cumbria's bicycle mayor for a year, made his comments after claiming that Botchergate, one of the main routes into Carlisle city centre, is unsafe for cyclists, caused by cars parked in the cycle lane and heavy congestion.
Mr Ingham told News and Star: "It's double yellow lines and there's a cycle lane there - though the lane itself is substandard.
"Practically every parking rule in the Highway Code is being broken, and they get broken every single day.
"There's a lack of consideration among some road users. We need to remember that it's not my road, it's our road.
"It just captured everything that is wrong with the way we should be travelling. It showed why we can't travel more actively."
He also pointed out that there had been 11 cyclist and 42 pedestrian casualties on this road alone between 2015-2019, saying his 'heart would be in his mouth' if his children were cycling on the road.
Making a wider point about the need for travel habits to change in the UK, Mr Ingham added: "There is no option but to change the way we travel.
"Switching to what you would call 'active modes' of transport, such as cycling and walking, would provide the answer to so many of the nation's problems.
"We're an unfit nation as a whole; obesity is a rising issue; but also, overuse of the car is also contributing to worse air quality in our streets. We know what sort of damage that does to people, particularly children."
