One Dublin councillor has said cyclists reporting dangerous driving to Gardaí could help with enforcement.
Green Party Councillor Donna Cooney was speaking as 71 fines have been issued to motorists for dangerously overtaking cyclists, or attempting to do so, in the past three years.
To date this year, 14 fixed charge notices were issued for the offence.
Dublin Cycling Campaign is calling for people to be allowed to submit footage of law-breaking motorists to Gardaí.
Councillor Cooney told The Pat Kenny Show anything would help.
"I've seen similar, say for dangerous and illegal parking, in other cities in Europe," she said.
"I think even in London they were giving people some sort of payment for being good citizens and reporting this type of thing.
"So I mean any measure that can work.
"I think that the Guards are over-stretched in terms of being able to enforce this type of thing.
"We'd like to see more enforcement, but they can't be everywhere at every time."
She said more reporting would also mean "more awareness."
'I'd love to see no fines'
She said the low number of fines is concerning.
"What particularly is concerning is this year with only 14 [fines]," she said.
"I could personally give those out in two weeks - I find people dangerously overpass at least once a day on a journey into the city centre and back.
"I'd love to see no fines being given out because there wasn't any dangerous overtaking.
"That to me would be really good because the message would come across and people are being considerate".
'It's never worth taking'
Councillor Cooney said she does not believe any decrease in fines is due to better driver behaviour.
"It's just about patience," she said.
"You don't necessarily get somewhere any quicker by over-taking anyway.
"You could just find that you're up at the next set of traffic lights a couple of metres ahead.
"It's never worth taking, and you're endangering another person's life by doing that.
"It really isn't worth it and you don't actually save that much time".
She said safer cycling conditions would mean more room for cars.
"Look at it this way: the more people that can cycle safely... means that the people that actually have to drive have more space on the road," she said.
"We're not going to make the roads any wider, the've been designed that way.
"Even if you did make them wider, it would just fill up with traffic - that's the science of it," she added.
