Yes, Tesla said that the base Model 3 will be under 6 seconds for 0-60, and I'm perfectly confident in trusting them to deliver on that.
"You realize that there are far more regular chargers across the nation than superchargers, right?"
You realize that the vast majority of "regular chargers" are L2 units putting out 6-10kW and are therefore completely worthless for long distance travel? And that the CCS infrastructure is woefully incomplete in the US? And that even if CCS were ubiquitous, the Bolt maxes out at 180MPH charging, which is terrible?
Plan a drive from NYC to LA using the Supercharger network and "regular chargers" and compare how long the trips would take. And that's assuming that the CCS units, which are often installed in single units, aren't blocked or broken.
