Paul Nigel Miley, 52, was slapped with a £1,008 fine for driving without due care or attention - despite not touching the rider as he passed her in a village.
Video from a helmet camera shows the woman toppling over into a ditch after Miley drove past her in his Land Rover Defender in Ashby St Ledger, Northants.
The footage was then submitted to Northamptonshire Police who said it "proved beyond doubt" Miley had shown no consideration for other road users.But web users were quick to leap to the driver's defence pointing out he'd left room to pass and the woman seemed to have got her feet caught in the pedals.
One person commented: "Can’t see what he did wrong.
"Looks like she just fell over cos her feet were attached to her pedals. Maybe she just needs to learn how to get off her bike!"
Another added "What a waste of everyone's time" while another put: "Where’s the offence? Honestly struggling to see what he could have done differently."
One wrote: "I think he could have slowed a little bit more but I wouldn’t have blamed him for her falling off! This world has gone mad! That poor driver!"
Another said: "Honestly. If someone had been on foot, stepped to the side and fallen in a ditch, it most certainly wouldn’t have been the drivers fault. He left plenty of room."
One woman said: "Laughable she was on the bike when the Land Rover went past - drama queens. Shouldn’t be in control of a bike if you can’t stay on it."
Others disagreed and sided with the cyclists, with one web user commenting: "A bit of consideration and appreciation of the vulnerability of cyclists would obviously have been better than driving close and fast.
"The woman could have fallen to the right and into the path of oncoming traffic on a different day."
Another put: "Agree he should of slowed down or stopped, however no contact and as others say she only appeared to come off as others stopped and she couldn’t remove her feet from the foot holders on the pedals."
Miley, of Ashby St Ledger, was fined, received five points on his driving licence and was ordered to pay £100 in costs and a £101 victim surcharge.
He had pleaded guilty to driving without due care or attention when he appeared before Northampton Magistrates Court last Friday (18/3).
Following the case, the force took to social media to share footage of what they described as the "reckless overtaking manoeuvre" on June 11 last year.
It shows the group of three riders going along the single track lane before Miley drives by as one cyclist shouts "slow down you ****".
After the car has passed the camera pans back to the middle rider, who can then be seen falling off her bike, while the other woman continues to shout expletives.
