I live a few miles from where this occurred. The sidewalk is right on the road (only on one side) it's 4 lanes with no crossing other than the light at the grocery store. You cross at the light, you have no sidewalk, you don't cross at the light you have to cross without a crosswalk. It's 4 lanes split by a row of trees, very low visibility, and every one speeds over the 45 mph posted speed limit. I wouldn't let my 13 cross that road and walk down it, much less at 6pm, one of the busiest times.
For context, this is where it occurred: https://maps.app.goo.gl/9GjCYGBAm5BBm8k59
All Chromebooks ARE Linux. ChromeOS is a Linux based operating system. Whether or not you can get to the lower level is a different discussion. I had one of the first Chromebooks, you have always been able to root them and do what you want with them.
