Foss is no solution, especially due to regulations (totally warranted, I want your car to have working braking systems...) and that this also involves systems at the producers.
- ldx1024 2y agoSoftware is only subject to entropy when you touch it. In most practical cases these days not being able to "improve" the software is a feature, not a bug.
- XorNot 2y agoSafety critical software is in a totally different league of development process to say, the infotainment system. The thing is we are basically at the point where infotainment systems should be on the way out - because the correct solution is basically "interface with the consumers phone". But any vehicle with software running which controls the brakes is either correct or unsafe when it ships - but you would never need regular maintenance updates to it.
- vv_ 2y agoSafety Critical Components (ECM, ABS, etc) need to be certified. This is very expensive and modifications are done very infrequently. I doubt that auto-manufacturers will use Embedded Linux for them.
- HdS84 2y agoYes, but what's about the components controlling speed, e.g. by detecting the speed limit from some map? Or the stuff implementing emergency calls? Also there is a plethora of features I (charging station maps) which probably need all maintenance, too.
