The man knocked off his cycle in a dramatic crash at Taupo a fortnight ago says drivers have to moderate their behaviour, before more people are killed.
David Joyce and his wife, Sirpa Lajunen, were hit by a car on rural Poihipi Rd and had to be flown to Waikato Hospital.
Speaking about the incident for the first time, regular cyclist Joyce said "badly behaved" drivers were putting lives at risk.
"I've had beer bottles thrown at me, young guys in their car breezing very close, people who beep the horn at you for no reason," he said.
Road cycling was one of the fastest-growing forms of recreation in New Zealand, Joyce said, but was dangerous because of the attitude of drivers.
