As a fellow TSLA stock holder, I absolutely agree.

The growing electric vehicle market has plenty of room for multiple manufacturers. Tesla by itself cannot grow faster without introducing quality issues and cannot make vehicles fast enough to transition the entire vehicle market. Other automakers are unwilling to invest in their own supercharger network and without access to high power fast charging they will be forced to produce plug-in hybrids for the foreseeable future. Opening the standard would help bring in more capital to build the supercharger network and hasten the transition to zero emission vehicles.

I think that over a certain speed, fuel economy goes way down.

This is because:
For high velocities drag will vary as the square of velocity. Thus, the resultant power needed to overcome this drag will vary as the cube of velocity. The standard equation for drag is one half the coefficient of drag multiplied by the fluid mass density, the cross sectional area of the specified item, and the square of the velocity.

I installed a wood burning insert into our fireplace. It has a large glass door so you can still see the flames for ambiance. It is 70% efficient, using a blower to circulate heat and is designed to reignite smoke to reduce particulates. I gather wood locally from trees my neighbors cut down after summer storms.

So I can heat the house in the event of a power outage. I also have an inverter so I can use my prius as a generator to run the blower, router, wifi.

Have you been to a non-electrified camping ground that allows RVs? People who drive huge vehicles towing huge campers and sometimes an extra vehicle, ATV or boat achieving a paltry 8-13mpg have absolutely no qualms about breaking out the gasoline generators.

They can't leave the comforts of home behind, including the noise and smog.

I live in Wisconsin where solar power is not great, but because costs have come down it is now close to being cost effective and I was looking at buying a system that would effectively cut my costs in half for 15-16k after tax credits. But after reviewing my house east/west facing rooftop and several nearby trees my solar potential was unfortunately deemed to be poor.

SRP does allow you to switch to Time of Day pricing so you could offset your air conditioning costs and then only draw electricity at the off peak rates. They also have installation incentives and there may be state/federal tax credits.

Because electric cars can (and should) be charged at night, they do not add to peak loads. Excess nighttime capacity will be sufficient to charge electric vehicles for quite some time. Additional renewable resources such as wind power will help to bolder nighttime grid capacity.

"It’s estimated that 75 percent of the 250 million vehicles on our highways could be charged at night on the current electric grid – without any new power plants"
