Musk said that his company is aiming to demonstrate a drive of this full autonomy from LA to New York, including parking the car, by the end of next year. The company apparently has been testing their hardware for the last 1 year.
These new cars now have 8 cameras for a 360 degree view of the surroundings and have a new computer, boosting the processing power by a factor of 40.
By promising to deliver a fully autonomous car by the end of 2017 , Elon Musk has show yet again that he is going to work with very aggressive timeframes. While Google has been working on the project since 2009, well know car brands such as Ford, Mercedes, and others are giving a 2020 to 2025 timeframe for their cars to become self-driving.
