   Speed *limits* are seldom observed -- the driver always thinks himself   
   more capable of determining what the speed limit SHOULD be.   
      
   Most of the "rotaries" that I've encountered have been out of   
   congested/city areas.  I can't recall any with "crosswalks".   
   Rather, they are typically inserted in high-speed traffic   
   (e.g., 65MPH) where multiple such roadways need to intersect   
   without the expense of a more costly interchange (e.g.,   
   cloverleaf, diamond, etc).   
      
   I think this is what terrorizes the unfamiliar -- all of that fast moving   
   *determined* traffic (THEY all know where they want to go) and no place   
   for the wary to sit and think about it (cuz there are other determined drivers   
   right behind them)

   We have a lot of trucks and off-road-ish vehicles with very high   
   clearances.  I'm sure *I* could drive across the mentioned rotary   
   in our SUV but it would be a jarring experience and likely would   
   screw up the front-end alignment.

   Here, people are just lazy drivers.  They think they KNOW how traffic   
   SHOULD work so are surprised when they encounter situations where   
   it defies their expectations.   
      
   There's one intersection that I *often* drive through yet always find myself   
   relying on the GPS to remind me of the actual traffic routing:  you veer   
   off to the right (in three lanes) and the road then crosses over the road   
   you *had* been on.  Immediately after doing so, you need to be in the rightmost   
   lane to execute a 90 degree turn (at much reduced speed despite the high speed   
   traffic immediately behind you -- so try not to get ass-ended in the process!).
