Re: [EVDL] Tesla mileage (was Solectria Sunrise Boston)

Speaking as someone who lives in the area, I can point out that two of
the trips mentioned have significant downhill sections: North Lake Tahoe
(Donner Pass) is at about 7000' while San Carlos is virtually at sea
level. Having made that trip numerous times, gas mileage is much better
the direction they went vs. going from San Carlos to NLT.

Also, the trip from Saratoga Gap to San Carlos has about a 2,000' drop
in it. But they mention "commuting" so maybe that includes round trips.

On the other hand, the round trip from Woodside to San Gregorio beach
(being round trip) is a wash; it does contain very steep hills and being
very twisty in places would be a blast to drive with a car that handles
well and has good acceleration.

I can only imagine what they mean when they refer to "aggressive
driving" on I-280. The speed limit is 65, but I get run over doing 75;
many folks routinely do 80 and the people I'd call "aggressive" are
doing 90. Driving like that, there are undoubtedly numerous
accelerations from 65 to 80+ as one works one's way through "knots" of
traffic.

If a conversion got the 50-60% of the mileage (over the same courses)
they report, we'd be home free.
