Tesla Cybertruck is notably the first time that Tesla is straight up not delivering on some of the key specs they promised
Promised specs:
500+ mile range
$70,000
Delivered:
340 mile range
$100,000
Tesla (and others) have taken the stance that the thousands of pounds of extra battery required to deliver 500 miles of range with today's battery technology is not worth the hit to driving dynamics. At this point I can't be surprised if Roadster 2.0 has nowhere near 600 miles of range either
