There's a good reason why the sport has changed in comparison to how it was 30/40/50 years ago. You can see that in every sport there's some evolution. In rallying much more than anywhere else as you are dealing with technology, but also with a constant changing society. Things that were considered normal in those days are (unfortunately) unacceptable today... Things like endless recce/training, even with competition cars, weeks before big events, were normal back then, but it almost killed the sport. Ask some well-informed person from the UK why there's almost no tarmac rallying left in the UK. Also the roadside service is something unthinkable today. Not only because it's unpractical for other traffic (cars and vans often being half on the road), but also because of the added danger of the extra "rally" created by service vans that try to meet the drivers as often as possible. Same goes for the rally on public roads as the Safari Rally was. Today it's hard enough already for organizers to make an event happen.
I would love to see longer events with more days, more different stages, night stages, mixed surfaces etc. But you have to be realistic. Most people here have more or less an idea of the cost of running a rallycar, very few have an idea of the cost of organizing an event... ;)
