I’ve been taking autonomous robotaxi in China since last year. It is still in trial stage, so the coverage area is limited. The ride was smooth, I felt safe, the screen shows what the car ‘sees’, and it was easy to book and pay for the ride. I see the looming end for taxi drivers.
I like chewy, but hesitant about Roku. I had their box previously, but didn't find it useful. A cheap android box from huaqiangbei is more than enough to replace Roku.
