Description: Biker lane splitting gets sideswiped by car changing lanes, the biker slides across 4 lanes of the CTE finally stopping in chevron markings. Extremely fortunate that all other vehicles were alert and didn’t run over rider. Rider mentioned he has bad abrasions and is due for an x-ray. As a biker, it’s safer to always wear appropriate protective gear and never speed while lane splitting. Happened on CTE on 20/11/2020.
