Driving through Cupertino neighborhoods, I've seen several homes with not one, not two, but three(!) Tesla's in their driveway.

When I wash my Model S in the driveway, people walking by will often come up to tell me how much they love their own Tesla's (or wanting to know how I like mine). Never had that happen when I wash my Audi :) The Audi is even the more expensive car.

You might already know this, but you shouldn't really be washing your car on the driveway, especially if you aren't sure whether your drains there are connected to the sewer pipes, rather than the storm drain. A Tesla will give off less oil products but there is still the soap (phosphate) and rubber dust. A car wash treats and recycles the water.

Kind of OT, but I agree phosphate pollution's a big problem and there's a lot of measures people can take to wash their cars responsibly. I've switched to just a bucket and low-flow pressure washer, which uses about 30x less water than a garden hose (and even less than my shower head, and unlike my shower, only runs when I pull the trigger). As a result, I have no run-off from the driveway, and what little water does get used is mostly recaptured and used to water plants. Honestly, at this point I think I use more water to shower, and I definitely take far more showers than I wash my cars.
