All but two of these things have ceased to be a problem for many years. Gasoline cars of today are extremely reliable and generally very quiet. The primary source of wear is road abuse on the chassis, given you keep up on oil, and any engine requires lubrication. The primary source of noise on the freeway is wind and road noise.
Many of the other issues with gasoline- smell, toxicity, stability- have been largely addressed by the distribution infrastructure.
Oh, by the way, gasoline isn't all that toxic. It is more hazardous for its volatility rather than any poisonous properties for humans.
Last thought- one of the two things that are still an obstacle (performance at extreme altitude) is firstly always going to be an obstacle for any type of combustion engine and secondly addressable with a turbocharger if you care enough.
