Every car manufacturer has done that for years. This scenario worked with bluetooth before Android Auto/Carplay was a thing, and AA/Carplay have been standard since shortly after the backup camera mandate brought screens to all new vehicles. I haven't had a rental car that required me to mount my phone to see navigation in 3+ years, and I haven't needed that in my personal (non-Tesla) vehicles for considerably longer. Tesla is strictly inferior to many manufacturers such as Mazda who manage to give you all of that without relying on a touchscreen.
