3 "pillars" that make rallying for me:

1. driven on normal roads, that are used for normal driving outside of rallies (else it's circuit racing or rallycross)
2. cars drive between stages on normal roads (else it's hillclimb)
3. cars resemble passenger vehicles that are driven and can be bought by public, resemble both in appearance, and method/style of propulsion. (else it's like autocross buggys, something "alien")


- so RWD cars from 1970s that nobody drives today are "historic" rallying for me, but not something to compete in on top level today

- when cars are run on petrol, rally cars should drive on petrol, when cars are hybrids, rally cars should be hybrids, when cars are electric, rally cars should be electric. At this very moment all 3 are available and used, so all 3 work for me). But running say on methanol like dragsters or something completely alien like an onboard chemical reactor (mixing 2 chemical components to generate energy) is just wrong for me. Similarly if in the future 99% of vehicles are electric, it would be wrong for me to have rallycars running on some synthetic petrol.
