Tesla is building a purpose-built, wheelchair-accessible autonomous vehicle, a company policy advisor told lawmakers in Washington, DC, on Monday.

But Tesla gave no timeline, no vehicle, and no details, and it’s not clear the “active product” is anything more than the Robovan it unveiled nearly two years ago.

Waymo has activated fully driverless operations in Las Vegas, its riders will now see vehicles with no human at the wheel, and the Alphabet unit says Denver, San Diego, and Tampa are next in line.

The move adds four new markets to Waymo’s driverless footprint and pushes the company deeper into its target of 1 million paid rides per week by the end of 2026.
