The current BS should be dropped and instead changed to be:
1) if a car is a parallel hybrid, or is a general purpose electric that gets less than 100 MPC (as rated by EPA), then they should only get 2.5-5K. The reason is that these will want to be charged during the daytime. That will increase our demand on power plants and grid.
2) if a car is serial hybrid or nat gas, or gets 100-150 MPC, then they should get 7.5-10K.
3) if a car gets over 150 MPC, then they should get 10-15K. THe reason is that they will charge at nighttimes, 98% of the time. As such, they will only use extra power and grid during the offtime, which will allow electric companies to move to smooth demand better (i.e., they can buy nukes, or batteries, etc).
As to the tax, the roads are not being paid for properly. They are falling apart rapidly all over the nation. By raising the price of oil base fuel SLOWLY, it gives ppl time to move off oil based and go to electric or nat gas. That will drop demand for the oil based, which will drop the price of gas/diesel. Simple economics. BTW, adding large amounts of taxes are total shocks to the economy. By adding it slowly like this, it allows ppl to make changes.
And as to the grid and power supply, numerous studies have shown that they are JUST fine, based on a couple of assumptions. The biggest assumption is that more than 80% of the vehicles charge at nighttime. As long as they do that, we are just fine. That is also why hybrids and low MPC vehicles are disasters to us. They will actually raise the costs to us.
Finally, BN is moving their diesel to LNG. If our commercial vehicles move to Nat Gas as well, it will allow us to walk away from imported oil. That will see fuel prices drop fast.
