As someone else already mentioned, a backup at the station of cars trying to unload could back onto the main rail, shutting the entire rail down, possibly for extended periods. Let's hope that the stations are easily expandable. I can imagine that this would be a nightmare at stations subject to flash crowds, such as event venues.
Second, one person struggling with the user interface would shut down the entire station until they figured it out and got their car out of the station.
I would change the interface as follows: Have terminals along the back wall where you buy your ticket and enter your destination. Then the terminal would program your destination into your ticket. Once your ticket is programmed properly by the terminal, *then* you go to the first available car, swipe your ticket at the turnstile and step in.
No. If you reuse it, it's easy to break. The Rosenberges went to the electric chair because some Russian spy reused a pad.

The primer seems a little overconfident about random ciphers
That's where I threw up my hands in disgust. I've never heard of a "random cipher" before. Did he mean one time pad? Those are provably unbreakable, assuming you have a good source of random numbers. Did he mean XOR the message from a cheap-ass PRNG? Unnacceptable. And why 4 bytes at a time? If it's just XOR, then 4 bytes at a time buys you nothing.

Even if you reuse it it is hard

Actually, the article was one howler after another. I cringed all the way through it.
Good gawd. I was on the development team of that box back in the day. It was the finest workstation of its era in terms of price/capability.
Should I be proud they're still in service, or heartbroken they're selling for $14?
