I just don’t think that the UK roads warrant this kind of addition! I was recently in the USA for four weeks and driving there is completely different. The roads are open, straight and driving can be pretty fun in a fast car. I am due to collect a model Y next week and I would potentially pay £1500 for the acceleration boost as a one off novel purchase. I would not however pay monthly for it. The only benefit I see is that it is not tied to the car as the one off purchase currently is. Depending on the cost of the monthly payment, this could work out cheaper in the long run depending how long you own the car. If I were TESLA, I would do it very differently and charge in the region of £20 a month for self driving, £20 a month for acceleration boost and £15 a month for premium connectivity. With those prices, so many more people would opt in and it would also mean that research and development would be easier because more people would have the additions and the software could be made better faster and in more countries.
