My only braking challenge with the Bolt was ergonomic my size 14 right foot was too big to rest comfortably on the footpeg without also resting on the brakepedal, so I was forced to ride with my foot at an angle.
That reduced clearance may mean the driver's foot could brush the side of the brakepedal when going from the accelerator to the brake, thus increasing stopping distances and the risk of a crash.
