I feel the exact opposite. I could present specific facts/make a giant argument, but no sense in some monstrous reply.

I believe Tesla is encouraging people who traditionally have held onto vehicles to upgrade faster, and this will accelerate similarly to how it has accelerated in smart phones as the technologies evolved.
One way to think about this is that emerging technology will have a ton of low hanging fruit where improvements are easier and more profound to the product. This will continue for years. As the technology matures, improvement is more challenging and yields reduced impact.
In Apple’s case, they’re simply addressing more of the market - and while the turnover rate for segments of the market may increase or decrease relative to the average, the overall trend is simply following the returns on rate of improvement. While the iPhone X user may not see giant technological gains to justify the iPhone 11 Pro, the users upgrading to the iPhone SE are likely seeing dramatic increases in functionality.
Applying this concept to Tesla - they’re in the earlier days still. The rate of improvement is dramatic. And I believe it will continue to be dramatic for at least 5 more years. I think the turnover rate of Tesla vehicles will grow during that time.
