The question is cost.
High quality epoxy primer and the following color and clear can add to the cost of the car. All car makers have bean counters running the show. Would you be willing to pay more?
I always spray thicker layers of epoxy primer down low and on anything facing forward. This adds to the flexibility in the paint. If you leave some of this in a cup it can dry to a rubbery texture. I won't list what I use because everyone has their own go-to products depending on where they live and the road conditions. Now it's not applied heavily, just enough to allow some give to the color and top coats.
I will say this though. When stripping any modern vehicles you can easily see that factories are using thicker layers of primer on the rockers and door lowers. On some vehicles you can scrape it off in larger pieces. The flexibility of this layer is what gives the top coat a lot of protection from chips.
Also, no amount of wax or paint protection will prevent rock chips.
If needed. I would pay more. Good thoughts!
Now case is ongoing and tesla needs to come forward with this really !
