While at CES I happened upon a Tesla Model X prototype. Last summer I placed a $5,000 deposit on this all-electric car, sight unseen. The plan is to eventually convert all our petroleum fueled cars to electric powered. The BMW i3 has proven to be a fantastic commuter car but the Tesla offers the promise of long range touring and much greater cargo capacity. Seeing the falcon-wing doors in person left me with significant concerns about the practicality of this design in the presence of driving rain or heavy snowfall. I will reserve judgement until I have had a chance to take one for a test drive, presumably about a year from now.
