EAP still seems like an expensive option to me and is of little use on country roads where I live. I am almost tempted though just for playing with the tech. Had a thought though - I think like any software if you buy it you should be able to transfer it to another car at a later date - just like installing Office on a new PC. That all makes me think these things could be stored with your cloud-based driver profile in future. This could even include performance enhancements and extra infotainment so if you rent a Tesla (or summon via Tesla network) you get all the features you've paid for in your profile. Gamification of options could also harness brand loyalty. My sons are mad on collecting extra details on Halo etc - if every time they bought a new Tesla or achieved a goal they got a different level of LED daylight logo on the back and on the main screen they'd love it. Stupid idea?
