Ramps, escalators, tiles, and seating. There is nothing inherently not accessible about subways, we just choose not to make them accessible. When I was in Japan, there didn’t seem to be any issue preventing wheelchair users, old people, or blind people from using the train system. Escalators can be used by people in wheel chairs and old people (and presumably blind people too, but I’m not sure.) There were tactile tiles in the floor to guide the blind, and there was plenty of seating specifically dedicated to old people, disabled people, and pregnant people. There were also wheelchair accessible cars on every train. As far as I could tell, it seemed just as accessible and easy to use for them as anyone else. (Also elevators were only usually kept open for the people who needed them)
Is own a grenade launcher for home defense, since that’s what the founding fathers intended. Four heathans break into me house. “Have at 'em lads” As I grab me scrumpeh and grenade launcher. Blow a golf ball sized hole through the first man, he’s dead on the spot. Quikie laucher on the second man, miss im entirely because it’s smoothbore and nails the enemy spy. I have to resort to the loose canon mounted at the top of the stairs loaded with cannonball, “Not one of yas going to survive this!” the double donk gibs two men in the blast, the sound and extra shrapnel set off car alarms. Grab me bottle o’ scrumpeh and charge the last terrified dadie prancin’ with a head full of eyeballs. He Bleeds out waiting on the police to arrive since triangular glass wounds are impossible to stitch up. Just as the founding fathers intended.
