This is cool and definitely interesting, but the title is really overselling what the authors are trying to demonstrate. Astra can "drive" a car at ~.42 m/s within a set of boundaries that are 2-3 times the width of a normal lane, on a closed course, with 0 unexpected obstacles, in dry conditions, in daylight for $7.74. And unless you start and then stop every few seconds while driving, this is barely considered driving. Still very cool and an interesting benchmark!
