I agree on the ATV issue, it's too labor and cost intensive for what you get from it. I drained my battery by day three trying to meet the demands and the cost to fix on top of the upgrades I needed, plus parts like fuses was just too much. I effectively haven't had an ATV since those first few days and I'm now on day 18. (Though part of that reason is my ATV plus half my garage somehow forced itself through the south facing garage wall and by time the ATV came out the other side it was totaled and one of the wheels went flying off).
Either the battery needs to recharge while driving or they need a station in the garage for hooking the battery to for a recharge (pre installed, not a cost to the player) Maybe at a rate of like 30% charge in 8-10 hours? That way you could leave it on all day for a good amount of charge or just charge it while you sleep for a bare minimum amount. Running the turbo hard and leaving the lights on while parked will still push you into the red even with daily charges. Seems like a fair trade.
Another thing I think is asking too much of the player is the radar towers for pings. As it is they go down too fast and cost too much for something that renders you unable to acquire money and have to trek out to fix. The two fixes I see best for this would be:
A) increase cost of fuses to maybe 350 each but allow players to repair them at the crafting bench for say 2 fuses + 1 scrap metal= 2 repaired fuses. That way you still need to keep them up but repairs are a reasonable cost to you while extra protection is going to get pricey.
B) Allow players to move the pins manually even if the tower is down. having the coordinates screen be 100% useless if a single tower goes down is too harsh. Maybe a down radar means that pin cannot be called for or used to call other pins. You still have a challenge on your hands if a tower goes down, but it's manageable and won't lock you from doing your tasks. Having two towers down will be a huge pain if your pings are far away but again it's doable in a pinch.
