What's your maths working there?
300m petrol vehicles in US approx - 1 per person.
Tesla will be making battery packs for 1370 packs per day (500,000 at max run rate / 365days).
300million / 1370 = 218,978 days to replace 300m cars. = 600 years of production to replace 300million cars.
America uses 20mbpd. 1/3 in cars supposedly (rest in aviation / heating / chemicals / shipping). So 6.66mbpd in cars/trucks/lorries.
You said "to replace 400k barrels". So that's replacing only 6%.
6% of 600 years = 36 years to replace 400k barrels.
That's my ballpark maths. What assumptions did you use?
The best way for america to reduce oil consumption is to stop driving trucks that get 10mpg.
Reduce/re-use/recycle was a 2nd world war mantra. Reduce is the quickest way to ween yourself off oil.
I always think no other industry works to make things so "inefficient" as cars. Lets compare to other modes of transport.
Shipping: containerisation for efficient storage massive ships (Brunel figured back in the 19th C that the larger the ship the more efficient it became). Propellors vs paddle-steamers. Long-sleek ships. "water-tunnel" test on propellors to get that extra 1% of efficiency.
Look at airlines: big airlines carrying 300-600 people crammed together. GM vs RollsRoyce 1-upping each other in efficiency. The Dreamliner - $10bn development to get a 15% fuel efficiency improvement.
Cars: I read once (US survery on new car features) # cup-holders ranked about 12th. 1 higher than fuel economy.
World is a bit crazy.
Fuel economy is a factor of drag which is based on rolling resistance (weight / wheel size), engine size (efficiency) car frontal area size and slipperiness (how streamlined). Neither of those 3 things are areas most people want to compromise on.
If you are really interested, read jhm thread on shorting oil to hedge tesla. The thread is now more on peak oil and relation to EV development. There is a ton of great information and jhm and neroden have some detailed math on peak oil.
