EVerybuddy likes to play the odds, correct?
OK, as a gambler, two scenarios:
First scenario, a private vehicle operated by one (animal of your choice, but probably one of the genus of hominids) in pubic (sp?) spaces (one might call this option the "unknown scenario"),
And:
Second scenario, a larger vehicle (generally easier for other vehicle operators to see, operated along a regular route, usually on a regular schedule) with one operator (variety, see above), usually watched by and known to one or more guests ("passengers", who may or may not be drinking a cup of tea, etc.), said operators employment income is derived from and relies to a large extent upon maybe more extensive training and maybe much more experience operating (one, more often two or more different types of) vehicles, again across pubic (sp?) spaces.
Place your bets grrrls and laddies!
(I might suggest the poor pubic (sp?) vehicle operator be given their own spaces (their vehicles) to operate said vehicles in relative peace somewhere other than mixed in with the "rabble"/other private vehicle operators and pedestrians, most of the time, plus other relatively tiny vehicles and their operators, some of whom (the operators) may or may not be "crazy" at least some of the time (especially those sneaky ebiker-types), all who obviously MUST be "crazy" to risk their lives mixed up even part of the time with other waaay larger and heavier vehicles.)
