Negative findings by federal investigators examining a self-driving taxi made by Amazon-backed Zoox raise questions about plans for a new generation of autonomous vehicles.

You might have heard — or read here at TechCrunch — about the “Waymo on Uber” robotaxi service that launched in Austin last week. I didn’t expect to see many of these robotaxis this week because of the road closures around the Austin Convention Center and side blocks.

It took a while, but Waymo is now servicing its HQ and the place it was born. I worked there 13 years ago and have seen it grow up.

Aspects such as better safety, smaller size, reduced congestion and convenience give robotaxis a promising outlook.

Motional is developing autonomous vehicles capable of handling a wide range of real-world scenarios. Its high-speed robotaxi testing reached speeds of 75 mph.

Avride has partnered with Hyundai Motor Co to expand its fleet of robotaxis, and signed a deal with the South Korean automaker to jointly develop and operate self-driving vehicles, the companies said on Wednesday.
