Piston Slap: Foiled by a Dome Light?

Peter writes:

I drive a 2010 Toyota Prius. From top to bottom, I’m thoroughly impressed by the technology in this car. And yet this engineering marvel is so easily disabled by its inferior owner leaving a dome light on overnight and draining the 12V battery.

Is there any technical reason cars allow the 12V battery to be drained down beyond the point where the car will start? Who needs that extra 6 hours of dome lighting?

Tassos The EQS is the best looking BEV, better than even the only Tesla I would ever consider (the S) and more luxurious inside etc etcThe self driving features will come in handy when I'm 110 and my eyesight and reaction times start to suffer.But that's four decades away, and only Tim recommends 40 year old "used cars"

Tassos The fugly looks of any Subaru, and especially the non-sporty non-elegant, fugly, low-rent looks and interior of the WRX are alone a sufficient turnoff to never want to own one.One can be a 100% car enthusiast but ALSO demand a beautiful AND luxurious vehicle one can be truly proud of and which makes one very happy every time one drives it.The above is obviously totally foreign to Subaru Designers and managers.Αnd who cares if they sell all they make? this is 100% worthless bragging, since they hardly make ANY. ALL of Subaru's models together, all dozen of them, sell less than the top selling Toyota or Honda or even Tesla sells. ANd furthermore, if you have the intellectual horsepower to understand it, bulldude, which I am 99% sure you sure as hell do not, it is NOT about the sales units, it is not even about the sales revenue.It is all about the P R O F I T S.Am I going slow enough for you, bulldude?
