>>1326034>False. Ever see the massive ventilation fans on the top of a train? This is to keep air circulating from outside of the train. False. Those are designed to cool condenser.
They have like 10-30% intake from outside, but that is not enough.
>High speed trains tend to be pressurised for different reasons, and use a system more similar to an aeroplane.Only reason is drag, and they are not pressurized like airplanes, they have similar HVAC setups, as on buses or trains, literally the same units.
>Because you will make the train less aerodynamic and you also ruin the air conditioning.Sometimes you need only fresh air, and not AC. Let's say it is +15 or +20 outside.
Sure, it will add drag, but that would be cheaper and better, than running AC.
>>1326043>Or you can be tired, or make a sudden move because you sneezed,Tired? Take a brake. Nobody is threatening you with knife or anything.
Sudden move won't do anything interesting as long as you don't ride SUV. You will probably even stay in the lane
> or get into ice or aquaplane and then die.Yes, but don't be a fucking retard. Check tires, check weather, check speed, check fucking road.
>No they don't.No, they do.
Narrow roads without any traffic separation (like barriers) and no guardrails around poles and trees are still most dangerous. Those are usually connecting oldfucknowhere and newfucknowhere, and no longer than 30-40 kilometers, and have speed limit of 60, 80, or 90.
On highway you have so many safety features built in, that you have to travel at least twice the speedlimit, while being drunk, and trying to rollover.
I don't know any shithole, where accidents on highway are deadlier, than on those relatively slow roads in forest or something.
