uhhhhhhhhhhhhhhhhhhhhhhhh what car are you driving, that's not even legal. literally, every single car I've owned and driven has been able to have its brake lights and hazards on when the engine is off. and that's the law.
There are some cars that are wierd that way.. here in India, my grandad used to have a Tata Indica, I remember that the brake lights used to work with the ignition off, but only the parking lights were able to be turned on. The Renault Logan we have had for the past 11 years, does not turn it's brake lights on when ignition is off, but let's you turn on all the lights etc.. Flashers are mandated to be able to be turned on even if the ignition is off etc.
What SKB described is pretty much the situation. The brake lights themselves don’t work with the engine off but the parking light part of the taillights still do, as well as headlights markers and DRLs. Flashers are always operable. 2012 Volkswagen Golf btw
Brake lights 100% work with the car switched off. I've worked on enough cars and moved broken ones around enough to know that as long as it has 12V available from the battery, the brake lights will turn on when you press the brake pedal. The positioning lamps staying on is a thing some German cars do whilst parked, and coming home lights is a relatively modern feature, but it's not the same thing. Edit: I just verified this with a friend that works with vehicle electrics and accident repair, and he says that to pass a UK MOT, when the brake pedal is pressed, every car should illuminate its brake lamps with the engine off, but not necessarily with the key in the barrel and not in the ACC position. In Japan it is mandated that cars need their brake lights to illuminate whether a key is present or not, which is why Japanese cars sold elsewhere do this. The same applies to hazards btw.
Just tested it to see and the brake lights only work with the engine off if it is left in gear. I normally have it in park before I shut the engine off so I wouldn’t typically see this. As said before the hazards always work.
While I agree that a better ignition management would be cool and desirable, unfortunately it's a very very complex and delicate topic.Not only (as you can see here) that literally every part of the world has it's own quirks and features there, keeping old stuff working without reworking them is also very tricky. The existing ignition logic stems from the very beginning of this game and it's such a central part that it's not trivial to change without breaking existing content. So I don't really see any big changes ahead...
Another bump. Especially now that we have the Wendover, it makes no sense for the display to be on at all times. I noticed electronic displays will shut off in a wreck, what would break if you tried setting it to do so when the car was off?
The etks and cherriers turn their DRLs off when you turn the car off, the sunburst and SBRs gauges turn their lights off whe you turn the engine off, guess they could do the same thing to to the FCV and soliad gauges? Also, when you stall the engine, it doesn't turn the DRLs and Gauges off as it's in the ignition mode and not OFF.. It turns off when you hit V and turn off the engine. (Cyberpunk pun intended)
Tesla is also one of the least reliable American vehicle manufacturer. Firstly, HV and LV circuits are integrated on the same board, which means if the inverter breaks down, the driver is unable to close the window(s), also using mosfets instead of relays is a big no in electrical engineering. Most "conventional" electric vehicles use a dedicated LV circuit similar to the 12V system in ICEVs. which powers the lighting, power steering, onboard computer etc, and come with a 12V to 48V battery pack (lead-acid or NiMH) that can be charged or disconnected during service/maintenance. The HV system is OFF when the vehicle is shut down. During engine start where the driver turns the ignition key or press the start/stop button, the LV system activates the HV system via a set of relays and performs a built-in test, READY indicator turns on after the starting process. Teslas on the other hand, the HV is always on, which might explain the higher self-ignition rate. Secondly, Tesla does not have a mechanical braking system and they use software update to fix brake failure problems. Software bugs are more common than mechanical failures, which means the brakes on Teslas are also less reliable than "conventional" vehicles. In conventional vehicles where mechanical linkages are present between brake pedal and brake pads, if the brake booster fails, the driver can still stop the car by hitting the brake pedal harder (same brake pedal depression distance, same brake torque). Imagine what will happen if the brake booster on a vehicle w/o mechanical linkage fails. Therefore, vehicle system should be mostly the same on EV or ICEV, the only differences are on EV, regenerative braking instead of engine braking, and recharge traction battery instead of refill fuel tank.
For me the Wendover electronics still stay on when the engine is off, as well as the parking brake lights of every cars.
