If I were Tesla's CEO, I would have just cut the driving range in the "Standard" models by 50%. $10,000 lower price for the Standard than the Premium. *Less weight *Shorter stopping distance *Lower auto insurance *Lower fire/explosion risk *Faster recharge https://t.co/aXU6zACL88

US Model 3 & Y Standard launch disappoints. Europe gets bigger discounts. Speculates $399 leases, future incentives for demand.

In the old days, used car dealers would learn how to tamper with the odometer. Some Chinese automakers are accused of selling "used" cars with 0 mileage on the odometer to fake sales numbers. If programmed correctly, your odometer should freeze at 999,999 https://t.co/Ly4JCwf3n1

Among the many negative reactions to Tesla's "Standard" models, worse ride quality. Tesla downgraded the suspension, which causes more body roll during cornering & less responsive steering. I would have just cut the driving range in half! Less charging time, fire risk, insurance:
