On a second note...
If heaven forbid or hell in this case - one "somehow" does end up in the Indio-Coachella area during mid summer -
If proceeding via eastbound I-10 thru Blythe and US 95 :
Either leave Indio no later than 630am or leave Indio after 1100pm during the night when ascending uphill out of the valley due to avoiding extreme hot daytime temperatures enroute towards Chiraco Summit to avoid potential overheating an engine while commuting - Outside temps in the Coachella Valley start at 90 to 95 degrees F as soon as the sun pops up over the horizon during mid summer...
If proceeding via southbound thru the Imperial Valley to reach El Centro and I-8 via Yuma :
I would much rather commute on the CA 111 route (east side of the Salton Sea) for two reasons....
1 - It is more scenic
2 - A bit safer than the CA 86 route known as the "killer highway" between Coachella and Salton City as there are more head on collision accidents that occur, while having to deal with a higher volume of semi truck traffic...
One will be present at over 200 ft below sea level on the CA 111 stretch along the south end area of the Salton Sea , so be prepared to do a lot of yawning if not adapted to the elevation climate and somehow maintain full alertness when commuting along the Salton Sea area on a prolong commute....
As noted, the desert southwest is very very hot at this time of year, and especially both the Coachella and Imperial Valleys are no joke - how I know is I was raised there in my teen years after being raised in the Los Angeles basin prior to that and in my late teen years.
Also noted - I too would opt to commute via CA 58 via I-40 with the addition to Needles, cross River Rd. into the Arizona side for a couple miles in Mohave Valley and top off fuel tank(s) at the Arco AM-PM mini mart station in order to NOT pay for someone elses retirement (if you know what I mean) - head back to Needles and proceed south via US 95 to Vidal Junction via CA 62 to Parker via AZ 95 and US 95 south at Quartzsite via to Yuma.
