Someone responds to Bardfinn's strange use of the metric system. Bardfinn responds about how she runs a terror-watch subreddit

minimum speed

Part of it is that they don't want you to drive slow to avoid the toll charge.

Part of it is that they don't want you to slow to 3 kph & haul out a SAM or RPG and fire it at an aircraft.

If D/FW airport were designed today, there would be an outer tier of parking and transit into and out of the terminals and absolutely no thru traffic for the general public.

Using parking regulations as a prompt to start talking about the optimum speed for firing a SAM at an aircraft is the most male-brained thing I have seen this year. No wonder xe gets mistered in the responses.
