    Tuesday 03/25 I drove my 2017 BMW i3-REx for 24 hours which matches how long it takes to witness a Starship flight in Port Isabel TX:
    Code:
    Tesla Model 3   BMW i3-REx
    1,200 mi.       1,140 mi.    distance
      $80.00          $81.00.    cost
    

    This was not a planned test between the two car as much as by accident, nearly the same distance and time. Lesson's learned:
    • overlap or serial biology breaks - you don't eat something while pumping gas. But it is trivial to eat a fast food sandwich while charging. Pumping gas is faster than charging but changing can occur while dealing with human biology.
    • Full Self Driving (FSD) or short gas segments - FSD handles the driving which reduces fatigue. However, the 2.3 gal gas tank in the BMW i3-REx means taking a fueling break ever 80-100 miles . . . a pause that refreshes.
    • Naps vs all nighter - no BMW i3 cat naps and drive as long as the driver is alert, catch-up sleep when you get arrive. No catch-up sleep with the Tesla as catnaps, a biology function, are easy while getting a charge.
    Both cars are equally capable of the same distance for similar costs over a 24 hour period. But they handle things differently. A happy human knows how to adjust to the vehicle characteristics:

    LATE UPDATE

    I learned about the problems with Electrify America (EA) nearly 10 years ago with my first, 2014 BMW i3-REx. On this trip, I needed to refresh my battery SOC and out of three charging stalls, only one worked. I had to change stations to WalMart. There I used a sun-bleached screen, older unit to add 64 miles (15.82 kWh, $7.94.) In that 20 minutes, the dogs and I got to do biology stuff. Compared to filling to the 2.3 gas tank:
    • 20 minutes to charge - about as long as the Tesla charge interval
    • 64 miles added range - the Tesla would add 140 miles range
    • 33% charger reliability - +99% reliable Tesla Superchargers and when one fails, move to a second stall
    • range extender cross country - Tesla EV both town and country driving
    One of the reasons for this trip was to look at replacing the 2017 BMW i3-REx with a HW 4.0 Model 3 or Y. This test demonstrated there is no pressing need so I have to look at confidence and sad to say, the Tesla is losing my confidence, Not the car but the distracted CEO.

    Finally got all of the fuel and one charging costs:

    For 1,140 miles in 24 hours minus 1 hr meetings but keeping biology breaks: ~50 mph block-to-block speed. In summary, slightly slower than an equivalent Tesla trip that overlaps biology and charging. Also, slightly more expensive over the $80 Supercharger fees.
