On #1: Adding mechoffer 3
It would be helpful to have a server-side check against the frequent Non-RP interactions roadside mechanics have: Arrive on scene, see flipped car, RP the hook (even though you can't hook onto a flipped car), ram the car to flip it, customer hops in (usually because desync means only 1 person can see the car upright), customer drives off (with car still RPly hooked to the tow), now PM the driver and inform them its a non-rp, hope they come back to continue, then you can do a roadside repair and charge them.
Essentially, towing a car damages it, so roadside repairs as a way to make money is fine. However, the lack of a mechoffer 3 means non-RP evasion and trying to get free flips happen too often.
On #3: A chink in otherwise impervious armor
LSC doesn't have a problem as large as this fence issue, but the lack of a gate on the staircase means people can easily lockpick bikes from the upstairs employee parking, drive them down the stairs and speed off.
The vehicle suggestions all seem very good, especially eliminating the useless utility trucks. Choppers are probably a stretch, but brainstorming solutions to the problem of stuck cars (to avoid needing admins) is a great move!
