Having a needle sweep for speed is more intuitive for quick comprehension on speed. This is a big deal in HMI design, and despite have high resolution digital displays many HMIs still have analog gauges for critical information that is needed at a quick glance(engine speed, temp, lube oil pressure, etc). The same translates to interacting with out vehicles. I love the idea of a tesla, but the whole interface panel LCD is a big downside to me.
