Google’s self-driving cars have driven over a million miles in autonomous mode. But when Google brought its testing program to Austin, Texas, one of the vehicles met its match: a cyclist doing a track stand – when a rider shifts very slightly forward and back to maintain balance while keeping feet on the pedals.
Whereas our brains can predict relatively easily how a car, pedestrian or cyclist might act, computers have to be programmed to recognize different patterns of behavior on the road.
According to a report in The Washington Post, one cyclist in Austin rode up to a stop sign at a four-way intersection and started track standing as he waited for the Google car to carry on. In his account posted on an online forum, he explains that the car apparently detected his presence and stayed stationary, struggling to work out whether the rider was moving forward or not:
The cyclist balancing on his pedals, while moving a tiny bit to keep upright, confused a computer’s understanding of how cycles behave. And while Google is continuing to refine its software, for now it seems they have some way to go before self-driving cars are ready to hit the road.
