I agree 1,000,000%... Cruise on TDU is fun, but it's annoying when you want to pass an AI car, or another player, but end up cutting another person behind you off because of no turn signals... Plus they'd be cool to use. Some more suggestions of what other things they should put in as well...
(1) Customization (Anterior of car)
- Customization of Bumpers, Headlights, Interior, Window Tint, etc.
(2) "Dirt System"
- If you drive your car a lot, dirt accumulates and you can wash it off (which leads into another section "Car Wash"... I believe there was a P.C. mod for a Car Wash).
(3) Gas
- If you get "low", then you can fill 'er up at a Gas Station.
(4) Headlights
- "Off", "On", and "High"... Also, possibly, Fog Lights as well...
(5) Riding w/ other people
- If you have a friend, you can get in their car and ride w/ them.
(6) Turning off your car
- When "sitting" for long periods, or whenever you want, you can turn off your car.
(7) Trucks
- Some Chevs, Dodges, and Fords, Toyotas, and maybe a British manufacturer (Ex. Land Rover).
(8) Windshield Wipers
- If there's inclement weather (Ex. Rain).
(9) Other specific things
- Ex. Oil Changes, Tire Blow Outs, etc.
...
Another thing to add (that's not a "Small" Change)... They should put in a "Cop Vs. Crook" or "Hot Pursuit" mode in it (where you can choose a Standard Cop Car [or customize one to be one]). Ex. Changing a (if there's trucks) 2010 Dodge Ram 1500 into a Police Truck... THAT'D BE COOL!
...
Anyways... That's what I'd like to see in the game... Peace.
