Just getting rid of metal structural components would be a huge boost, that's why the Cabri G2 has zero life limited parts while the R22 has... many. The state of civil rotorcraft is analogous to that of commercial jets 25 years ago. All metal parts, little to no computerization. This isn't inherent to flying cars vs. conventional helicopter configurations, just due to the extremely risk-averse nature of the rotary-wing industry. Helicopters today are very under-optimized but still work pretty well. Think of how shitty old cars were in mileage and maintenance, but still got the job done, while new cars typically last over 100,000 miles.
