I recently did SW London to Nottingham and back, it is doable on one charge but I stopped at Milton Keynes Ionity to top up and got around 260kWh, there’s a cafe there too.
DO NOT install the latest Tesla Update! Random alarm activation, phone not working properly and taking 3-4 mins to start up are some of the symptoms I've had past few days. Anyone would think it was Porsche software ?. On the plus side they will fix it in a week or so.
