"Everyone has them in their local streets and local highways and when they're dangerous, then you report them to authorities," Morrell, a U.K. resident, told Daybreak North's Carolina de Ryk.
"Then they don't do anything and then you have to get the police involved. And I thought, 'I'm not prepared to live in a society that accepts that.'"
Morrell worked for more than 25 years in road structures and reinstatement, and has studied roads around the world including Canada.
"To some people they're an annoyance. To some people they cost them quite a few buck in terms of paying out for repairs.
"But unfortunately I have met some families of some cyclists who were killed …. so there's a tragic side."
Morrell has launched a social media campaign calling for better road repairs, urging people to post pictures of potholes and tag their relevant authority.
So far, he says, the results are already encouraging.
"I've had some tremendous successes, where even MPs over here couldn't get roads done ... I've got involved and used social media and surprise surprise, we've got repairs."
