Shoot, here using indicators would be a luxury, most vehicles rarely have working lights at all, you often see a vehicle driving at night with the only working light being one headlamp, possibly even aimed at the road.
I did call the RTI one evening to report a HGV driving without any lights at all, aside from some very dim working emergency lights. They pulled him over, fined for the non working lights, and also found the vehicle was otherwise not roadworthy and overloaded. Helps to have the direct number for the control room, and they tend to want to keep these moving wrecks off the road, so they do not have to clean up the aftermath.
As to panel design, often the function is overruled by appearance, so you might have lamps that are obscured by the steering wheel at times, or are not easily visible, or are just plain too small, to fit in the style. Like using a 2mm diameter red LED as an engine temperature warning light, and a 15mm blue LED as a bright beam indicator, right next to each other. Then run the red LED at glowworm level, and the blue at laser light level. Gauges that are tiny, and obscured by most driving positions. Then add a display that tells you all sorts of things, like the fuel range, transmission settings, mirror positions, seat positions, but that does not tell you coolant level is low when driving, or that the engine is approaching nuclear meltdown because the radiator hose ( which was recalled 6 months before, but the dealership did not do, despite having the vehicle in at least a dozen times in the interim, and having the hoses in stock for this) was known to break at the engine side.
