I decided to say screw it and drive the Tesla until I pick up my parents on Thursday. It will have been right around 3.5 weeks of driving and none used any gas - in the other cars I own.
After the charge at Tesla last week, I drove until I had about an 18 mile range and decided it was time to plug in. I could have run it down a bit more, but felt it to be safer than sorry. At 25 miles a dashed yellow line appeared on the gauge that shows the power consumption (think tachometer) I didn't test it, but I'm pretty sure it was a limiter. I could only use about 160kW if I stepped on the go pedal. I imagine it gives you just enough oomph to merge, get up to speed quickly enough without being a danger.
Since I have to give the car back in a few days, I've started to have a little more fun with it and not try and drive green. The acceleration never gets old.
The heat did kick on twice late night, but only enough to keep the temp that was set. I could smell the "newness" of the heater. No noticeable drop in consumption either. I believe the A/C was still on as the air coming out was not cold, but cool.
Nothing really important to report. The car just works. It gets a lot of looks, thumbs up, especially since it's red and stands out a bit more than the other colored Model S' that are around town and there are a lot.
One final report after I hand the fob back....
