Dad has it on his Corvette, and I find it incredibly distracting. It's not like I need to hyper focus on the speedo or other gauges like my life depends on it - takes a fraction of a second to quickly glance down to see my speed, and that's only if I don't have cruise set..which it is 99.999% of freeway time. Another fraction to scan the other gauges to see if anything is abnormal once every few minutes.
I couldn't give rat's behind if my temp is 220* vs 223*. I just need to know if it's outside a normal range. I don't need to get exact fuel level every 5 seconds.
I get why a fighter pilot may want to know the status of a dozen systems RIGHT NOW, but it just seems like a solution in search of a problem in a car.
