The truth is that IF the Tesla had a transmission, the performance would be even more impressive. The 0-60 time might not improve much due to adhesion limits of tires, but the top speed could certainly be increased. So... it's not that the transmission was "useless", just that Tesla determined they could meet the minimum performance expectation for the majority of their customers (ENOUGH) to be happy without including the additional cost.
Also it was unreliable and kept breaking down.
I agree that for the most part - the buying public is leaning towards a compromise of ease of use over outright performance in EV. I am hopeful that there will still be those among us that continue to push for performance though as we show the way for what is possible.
This seems to be the consensus in our little unplanned poll. Most of the supporters of single-gear have been making the point that they get plenty of power for all their needs from EV's with a single gear. The supporters of transmissions have been pointing to racing or squeezing out a bit more power in the lowest gear.
There are costs and benefits to both, everybody does their own calculus to determine what fits their wants and needs.
Thanks for your insight, Brian!
