Hmmmm. This is very strange. When I ordered late last year there was no mention of only 1 year data included with the purchase. It’s certainly not in the terms and conditions.
Other manufacturers usually provide 3 years, and it’s clearly stated.
I know it’s ‘only’ £10 a month but I might get in touch with Tesla to show me where this is stated at the point of order.
I ordered in August last year and definitely remember it being mentioned when I was looking at the options while considering ordering. I can't remember the exact wording, but it did make me aware that it was a "trial" and I seem to remember being aware that it was 1 year, as I asked the person from Tesla who accompanied me on my test drive for more information on what the billing amount/frequency would be after this period (he didn't know.)
