The only thing that is going to get Tesla to change course is competition, and people actually putting their money where their mouth is.
As it is, and has been for a long time, Tesla appear to enjoy demand exceeding supply of their cars. They know they can be insouciant towards individual customers with complaints or concerns because there will be another 3 behind them keen and ready to take their place. This mentality trickles all the way down through the company. You might get individual employees who take pride in their work, but in the main the whole attitude towards the customer - in build quality, quality control, PDI, after sales, etc - is perfunctory.
Before too long Tesla won’t be remarkable as “the only fully EV brand”. Others, with better attitudes, solid and proven manufacturing processes, big glass buildings that customers can walk into with complaints and concerns, will have established themselves and will be luring customers away for whom just the brand name “Tesla” is not enough.
Sadly I fear that the point that they try to change course and dramatically improve things will be too late for them to recover from, and Tesla will become synonymous with “the car company who were first to market but squandered their position”. Maybe that’s too extreme and they’ll always be a place for them, I guess we’ll see.
