@xs4me2 @luckytran One problem with the social distancing guidelines was aerodynamics: at stores in our area, they'd have people line up outside keeping 6 feet apart along the side of a building. The problem is airflow over the building is turbulent and you get eddies that move air in circles adjacent to the building: the viruses blown away can come back at you due to the circular airflow. Example:

@xs4me2 @luckytran The case I mentioned was an important one during the pandemic: we shopped as quickly as possible (e.g. for food), and would usually spend more time waiting in a line placed on the downwind side of a building than we would spend in the store. Neither local public health officials nor the store management thought about aerodynamics.

@soller Make that "dumb convicted felon"! Many years ago, in an unconnected world, an immigrant climber, Rupert K., got speeding tickets in every jurisdiction between the Bay Area and Yosemite. The story going around was that Rupert would show up in court wearing Austrian peasant garb, and say "am but humble peasant from old country," and would get sent to traffic school so the DMV never found out. The Donald doesn't know when to grovel.
