Why are many cars’ screens slow and laggy when a $400 phone can have a smooth performance?

First, the electronics in cars has to survive a range of temperatures that would melt a consumer device. Cars are a very hostile environment. This limits technology choice. Second, everything in the vehicle needs to be certified and crash tested. There is tremendous liability for car manufacturers if something causes a crash or an injury. This makes manufacturers cautious.
Together, this limits technology choice and takes time and is very costly. Which means anything in your vehicle was probably invented and tested rigorously more than 10 years before it was designed into the vehicle, which was about three years before the vehicle was made. Your newest $400 device has components that were invented a few years ago, and the software was probably installed a few months ago… so it is about 3 generations ahead.
