Right, read my post again. I used numbers for regular charging. I did that for 2 reasons. First even though it's only $300 to upgrade to level 2, in many people's cases you'd have to get a second line into your house. That's expensive. Second, I'm not confident that level 2 charging is easily available in the wider world which means you need to plan for a shorter round trip or, again, plug in over-night.
Everyone gets a 240V connection, usually about 30 amps, and charges at 7kW at home, adding 224 miles in 8 hours.
If you want to go more than the 200-300 miles your car goes, you stop for 15-30 mins to rest while you rapid charge.
To quote the page you linked to:
The Tesla Supercharger is the fastest charging option when you're away from home, allowing you to charge your car up to 200 miles in 15 minutes.
and
A Tesla Wall Connector offers the fastest charging speed for your home or office, adding up to 44 miles of range per hour charged
Honestly the expense of getting a second electric line into the house is one of the two things that's stopping me from replacing my gas-powered car when I give it to my daughter. I'm pretty sure I'm not the only person in that situation.
Maybe when the rapid charging infrastructure is well-established what you describe will happen. One thing I believe though is that when cars with a 1k KM range hit the market it's going to make cars with a lower range less expensive and that will make everything you say easier for people to swallow.
