Well said.
What's striking about the Amazon/brick&mortar comparison is that retailers' senior management did recognize Amazon early as a fundamental threat. (For example, Walmart.com came to life in 2000 and was set up in the Bay Area with plenty of love from the Walton family.) But on an operating level, few retailers' managers wanted to change the business rapidly enough to deal with it.
They fell into the Kodak trap of sticking with the old ways for a few more years of higher margins ... and thus building out online versions that were way too timid and deferential to make it big.
For example: limited supply of hot items? Put them in the physical stores, not the online one. Price war online? Can't compete, because it might mean undercutting the retail-store price and hurting high-margin sales.
It will be interesting to see if the car companies are able to build out new transport platforms that succeed by making life much worse for their existing dealerships. If so, they can give Uber a run for its money. If not, they will compete in slow motion.
