He said this was because helmets had connotations of danger.
He didn't say whether seatbelts put people off driving.
Mr Gummer pooh-poohed the idea that cycling without a helmet was dangerous. "So's driving," he said.
At least he didn't roll out the old argument that more people die of obesity because they don't want to cycle with a helmet - therefore the helmet law is killing fat people.
I wonder what Mr Gummer would say to the parents of the teenage Bay of Plenty cyclist who's today in hospital with serious head injuries after crashing into a truck yesterday afternoon. He hadn't been wearing a helmet.
People who go out of their way to spread the message that helmets are not necessary, not cool, or even dangerous should be ashamed.
