Surely, and I could be wrong here, but if a moderately sized asteroid haphazardly punches a hole slap bang in-between, let's say paternoster square & paternoster row in london, then no matter how much invested in anything, will actually do anything but momentarily (micro or nano second-ish) slow your transformation from relatively dense combined atoms into their bright & vaporised disparate counterparts.
Rest easy, as the same sort of thing would already have happened a few micro or nano-seconds earlier, to those unfortunate enough to be within the strike zone of any incoming hurtling heavenly body - so why worry?
For those in London and the south east, deciding where to go if our fair, gentle, slopping sectioned part of the country were unfortunate enough to be in imminent danger of being wiped off the map (by a 200m asteroid), would have to consider making plans to journey at least 100 miles away and somewhere in a ditch, before coming close to having a 51% chance of survival; with the added hardship of many degree burns, loss of mobile signals and nothing handy in the nearest tesco metro.
The choice, therefore, is simple: voluntarily head to coventry, or be wiped off the face of the planet, or spending thousands or millions, and briefly cocking two-fingers at every one else and laughing as they're being vaporised, before you to end up in the smoke cloud.
Coventry, wiped off the map, disapprobation? Coventry...
