Don’t you have an option to boot from usb in the BIOS?
Note that accessing the boot menus is not always with F12. Sometimes it’s also ESC, F1, F2 or DEL. You should try those.
Most rulers will not care about this. Some people of their armies being killed is not part of their self interest.
In fact I can even give you some examples of rulers starting wars against countries being able to defend themselves, even though they knew they would have losses.
Even old blind people who can’t pass driving tests use Uber or Lyft, because public transport simply isn’t safe or suitable enough for them, especially during grocery runs.
You are assuming a car centric city here. In a walking and transit oriented city, it is safe and suitable for blind people to be independent and move by themselves. Only cars make the cities unsafe and the lack of transit makes it unsuitable to use something else than a car.
I understand that it’s not possible for everybody (though it should) but regular and long enough sleep will allow you to wake up without even needing an alarm.
This can be difficult during your studies with irregular schedule (and too many parties) or some jobs with irregular working hours. But generally if you wake-up everyday at the same time to go to work and you had enough sleep, you will be awake when your alarm rings.
