A couple of thoughts on "service & other" (S&O),
First an observation : there appears to be some annual effect going on in the S&O line. The Q1 as a % of auto is higher than other quarters. Given that Q1 is a low-driving-miles quarter you'd expect that Supercharger income to be reduced. So that would mean that service income is up in Q1, which might make sense. Now it is possible that Covid-19 has messed the driving-miles-per-quarter and corresponding charger use, but anyway I throw it out as an observation. If we had other information we could probably intuit something about S&O fixed costs, and relative profitability of sales (presumably always -ve) vs service vs chargers.

Another observation is of course that it has moved into positive GM% territory earlier than my own forecasting had assumed (I like being too pessimistic, if only that was also the case in Energy).

So .... a question for people with industry experience. In a typical legacy auto dealership,
1) How many cars are sold each year,
2) How many cars are maintained each year,
In other words how well is Tesla doing by comparison with a typical legacy outfit ?

Whilst I'm at it, here is how the charger situation is evolving. Personally I would prefer to see the trend reversing as it makes me worry about the qualitative user experience. I'll admit that the charge-rate improvements might be occurring at a faster pace than the deterioration in the connector contention ratio, so that the effective contention ratio is still satisfactory. But until one can see more data that is not discernable (at least by me).
