In an environment where control systems are already digital/computerized for valid functional reasons, adding a display screen is more cost effective than analog instruments.
I am old school and I prefer the analog style; however, it is fairly easy to simulate analog instrumentation on a digital display and some manufacturers are doing it very well.
All that being said, EVs are still a low volume specialty product that hasn't reached mass market status yet. Once they do, cheaper, more stripped down models will become available.
