A Tesla Model S has rear-ended a fire truck parked on a freeway in the US. The driver, however, says it wasn’t his fault, blaming the state-of-the-art technology instead.

On Monday morning, the Tesla car, going 65mph, hit a parked fire truck, the Culver City Fire Department tweeted. The firefighters were there attending to a “freeway accident,” when their truck was hit by the electric-powered vehicle, which was travelling on autopilot, according to the driver. The truck apparently sustained only minor damage, while the hood of the Tesla seems almost completely smashed.

According to Tesla, the Model S’ “autopilot capabilities [are] designed to make your highway driving not only safer, but stress free.” However, the feature is “intended for use only with a fully attentive driver,” according to company officials cited by media.
