No-one particularly 'enjoys' snotting....
The causes are down to the irritation of your sinuses, generally caused by wind in eyes (faster worse), air temperature (colder worse), humidity, and level of exertion (higher worse).
I have wrap round glasses, but find a get a big build up of 'fluid' - it's a bit tricky fiddling round with a hankey in built up traffic at speed.
The only time when this I find this isn't a problem is on the track, but the atmosphere is very dry and the temperature is generally warm.
I don't do it around people (pedestrians/cars/cyclists) and carefully aim for the verge.
