Toyota Sienna Incident

A May shuttle began a test shift on experimental software in a parking sub-lot. The vehicle exited the sub-lot and rolled over a curb. The vehicle stopped at a stop sign at the exit of the main lot. As it proceeded to turn onto the main road, it rolled over another curb. Almost immediately after rolling the curb, the vehicle began to drift right in lane, rubbing the vehicle sidewall on a curb. The test driver intervened immediately, but not before the sidewall of the rear right tire was weakened. Later during the drive while under manual control, the sidewall fails, eventually leading to a low pressure indicator illuminating in the dash. It was discovered that the deployment of map files, which must remain compatible, was incomplete, leaving a mismatch in the system. This resulted in the vehicle having an incorrect estimate of where lanes are in the coordinates of our localization map, and as a result, the vehicle had an incorrect estimate of proximity to lane boundaries, resulting in curb strikes.
