For companies and business travelers, this is perfect. Let me elaborate: If you purchase an asset, that is seen as a store of value so you need to spread out the tax reductions over the useful life of the product. But like this, self-driving is taxed as a service, not as an asset. That means all expenses are immediately fully deductible. Also, that means you can buy an affordable used car, gain full tax benefits (because the previous owner waited through much of the useful tax life already) and then upgrade to self driving and get full tax benefits again. For me personally, that means this feature would be effectively free because the tax savings cancel out the price.
