I think the new horizon 6 should put in a gas use feature. That allows us to choose different fuel cells and fuel pumps in the upgrades menu that gives us a HP boost. But also increases the amount of fuel we use. Make it so there are tons of gas stations all over the place and you have to fill up your vehicle at the gas station to keep running.
when you refill your gas before you run out, you will refill for free and get a small HP bonus. Have the option to choose unleaded for a small hp bonus and free refill. or choose race fuel for a small fee and increases the hp even more.
Then have a feature that if you run out of gas on accident it deducts the small fee to refill the tank and your reset at the closest gas station with a full tank ready to go again!!
This optional feature will make it feel more life like. It should have a on off setting like other assists so a player can choose to turn it off if they wish, but they miss out of the small bonuses to their HP for doing so.
this will HUGELY promote more car meet up spots as favorite gas stations will pop up next to the best drift areas and drag race areas. and will promote players meeting up at these spots and start having more convoys for street races and drifting!!! imagine how much more fun it would be to just log in jump in your car head to your favorite gas station spot where guys are taking turns fill up race gas and once everyone is topped off heads down the road to do some drag races with guys cycling out back and forth from the races back to the gas station to top off or get the bonus again depending on if its a perm bonus or a time lapsed one. etc
just imagine how much more interactive and community based the game would get! and if they put in some, somewhat basic. but more abilities to tune like let us choose things like fuel pressures and timing and boost pressures. etc nothing crazy complicated but enough that it makes the cookie cutter builds aren’t staples. and makes to identical cars have a chance at edging out a win over the other one because of a slight tune difference. they could even incorporate if its rainy the cars run fatter, or if its a hot sunny day. versus if its a clear night the cars start to lean back out and make more HP thus promoting to the night races just like the real thing!!!
