When they start selling cars only powered by batteries I'm going to
invest in a tow truck business.

The time has arrived:

And a good place to base the new tow truck business is about half way
between SF and LA, because that's about how far this $100,000 car will take
you.

Scroll to the bottom of the page.

Or half way between LA and Vegas.

The page leads to some "interesting" information.

If you cruise around you find claims that the energy usage is 110 Wh/km,
and recharge time of about 3.5 hours.

110 Wh/km is about 11.7 kWh for a 100 mile trip.

If the charging process is 100% efficient (not in this universe), to
recharge in 3.5 hours requires 11.7/3.5, or about 3.3 kW.

At 120 V, that's 27.5 A, which is a bit beyond the standard 15 A outlet.

At 220 V, that's about 15 A, so you better have a 220 outlet nearby.

Elsewhere they talk about recharging in 2 hours with some 70 A system.

Anyone out there got a 70 A plus safety factor outlet in their house?

They talk about "With your electrical company's incentive pricing
factored in, it will cost you roughly 1 cent per mile to drive the
Tesla Roadster".

Keep in mind they are targeting California.

In California, the "incentive pricing" is the more you use, the more
you pay per kWh.

There is the quote "Single-occupancy access to all carpool lanes".

Yeah, true for a while, but all the permits that are ever going to
be issued were issued long ago.

Just too much hype and inconsistancy for me.
