I'm 5'3" so there is no hope of my reaching the entire windshield, unless Tesla were to offer a "oops your air bags broke and the car is laying on the battery belly pan" mode-- which isn't going to happen---
In the past I've owned my fair share of SUVs. There was a European market only Bilstein suspension kit that I ordered from a UK vendor (and had shipped across the pond) for my 2012 Touareg TDI, and it lowered the vehicle down about 1.5" with new springs/shocks-- and even then I still had to stand on the front tires to clean the glass. Short people problems LOL
PS: For all of the Tesla vehicles I've ever had that offer SAS I've always set it to ALWAYS for Low setting. Just looks better-- tire wear be damned!
