As I wrote, I compared the Tesla lease price to an Audi S7 lease and a MB CLS550 4 matic lease. (Wouldn't you call that the competition?) And the Tesla was less.
People who lease cars are not "spending around $100K." They are figuring an acceptable monthly expense. When comparing the monthly cost to lease a car, who wouldn't consider the gas savings you get from leasing an EV. At today's gas prices and 15K miles per year, the savings are about $200 per month as compared to a car that gets an average of 20 miles/gallon. If a Tesla and and Audi have the same monthly lease price, the Tesla is really $200 less per month because of gas savings. Not saying it will change what you decide to get, but it is a factor.
