Bugging out in a normal size vehicle will only be possible when the bulk of the population hasnt figured out SHTF is happening yet.
One example how this could happen might be :
It's 1 am and you just figured out from the latest report that infections in mexico city (from whichever bug is in the maintream news right now) are up to 10,000 w/ 1000 deaths. This coming from only 100 infections and 5 deaths in less than a week.
That tells you, its deadly and fast and coming to your neighborhood soon..
.. so you bug out in the middle of the night,.... it will be many hours perhaps several days, before the maintsream panics and absorbs whats going on.
But you dont want to take the chance that they will catch on by morning and leave NOW.
You may even have some time to fill up your truck with sacks of rice...
You can find such Intel here BTW (even that post is still not a sticky yet I dont know, ????):

But short of a "lucky" early start like that,... I think it will be basically impossible, for anyone living in an urban area or even a suburban area for that matter...to get out to a BOL "in the country"
Think about how even a single accident can cause a huge jam in a normal environment..
Then add 10 times the cars and you dont even need an accident and u r looking at multiday traffic jams where people will have to abandon their vehicles and the preps within(!)
My recommendation is:
Unless you can be reasonably SURE you are beating the crowds to the roads... stay..at least then you have your preps, even if you have a nice BOL elsewhere... because being stuck in a jam in the middle of thousands of people will be veyr dangerous.. and a car/truck in the middle of a jam are even less defensible than even a small apartment.
That situation could be a death sentence.
Another solution is a motorcycle, but this cuts down on the amount of preps you can carry...and for folks with small children its a non starter.
But it may be the only way to get to your BOL.
(Hoofing it ,might be deadly since it takes long.. and that might just be long enough for the situation to go into phase 2... this will make long term travel on foot very hazordous and impractical for all but the fittest and best armed.. )
PS: I am sure this will be yet another example, of a sound and fact based operational analysis, not gathering "likes" or attention as much, as some mere opinion pieces w/ little sound analysis often tend to get.
