A Shimano neutral service car at the Tour of Flanders today knocked Trek Factory Racing rider Jesse Sergent off his bike, with another incident seeing a Shimano vehicle rear-end an FDJ.Fr car that had stopped to provide assistance to Sebastien Chavanel – the impact shunting the French team's car into the cyclist.

Here's the incident involving Sergent, part of a seven-rider breakaway group and who was confirmed afterwards to have broken his collarbone.

Here's the one which resulted in Chavanal being knocked off his bike – he too took no further part in the race.

During the 2011 Tour de France a car belonging to host broadcaster France Televisions swerved into the path of Juan Antonio Flecha, then with Team Sky, causing him to crash and cataputing Vacansolei-DCM's Jonny Hoogerland into a barbed wire fence.
