That jaunt is littered with Cali idiots that refuse to get out of the fast lane. Both ways. It would give the brakes a good work out.
I have to laugh at that. I would never drive n I-15 between 0700hr Friday thru 1700hr Monday. It’s “bumper car” or worse
and the CHP does what it can to slow it down.
It’s fun and games on I-15 till the CHP gets there!
