  • the effect is strong for sigma > 0 because dawdling is not taken into account when estimating approaching/passing times (fixable with parameter ''jmSigmaMinor'')
  • the effect is still observable for sigma = 0 because the priority vehicle assumes the worst case scenario (foe vehicle may brake while on the intersection) and brakes accordingly (fixable with parameter ''jmTimegapMinor'')
  • the minimum time gap of 1s was only being applied if ego and foe vehicle had the same target lane (fixed in ca2a88c (aka r26434))
