Nigel Hall, for the Crown Prosecution Service, said Princess Yachts carpenter Mr Stevenson was cycling home from the Coypool site.
He added that Nodder was driving his BMW in the opposite direction and came towards him in the middle of the narrow road.
Mr Hall said: “The defendant had his head down and was not looking where he was going.”
The barrister added that Mr Stevenson remonstrated with the driver to get him back on his side of the lane.
He added that a short time later Mr Stevenson was knocked from his bike by an impact from behind.
He added that the bike, a high-end machine worth £5,000, was fitted with a GPS machine which showed its speed going from 22.7mph down to zero at the moment of impact.
Mr Hall said that Nodder had a previous conviction and a road ban for driving without due care and attention in 2014.
Michael Green, for Nodder, said his client suffered from learning difficulties, anxiety disorder and Obsessive Compulsive Disorder. He added that Nodder had suffered a breakdown several years ago.
The judge said "There is no doubt at all that you suffer particular difficulties which would make a prison sentence particularly difficult for you."
