My survival transportation is predicated on the ordinary, low-key vehicles that I have now (a Kia Rondo SUV and a GMC Denali), plus bicycles that are slightly "tricked out" for durability.
One of my bicycles has a hitch, and I have a bike trailer that I can use to transport lots of material. I also have saddle bags that hook up to the bike.
My bike:
1) Requires no gasoline or diesel fuel.
2) Can be maintained (and parts replaced) with simple tools and a layperson's knowledge.
3) Is silent.
4) Is easily concealed.
5) I anticipate medical care will be spotty and in short supply, so regular bicycling will help protect against heart disease, diabetes, and high blood pressure (among many other diseases).
6) Bicycling does not display one's wealth in the way that the fancy batmobile does, so--theoretically--less of a target for looters.
7) I believe (and please note that I said "believe," and not "know") that a bicycling lifestyle keeps you more aquainted with your neighborhood, the weather, the changes around your home, and so forth . . . so one is in more of a position to be informed about the circumstances of one's environment.
8) If one is escaping criminals or thugs, a bike allows you to ride where most vehicles can't . . . and you can outdistance the criminals on a bike path or railroad tracks.
9) Some bikes can be easily folded up and kept in a vehicle as a "life boat" in case you break down or run out of fuel.
As for how I worked on the bike to make it a survival tool, I put Kevlar tires with Kevlar tire liners to prevent punctures, I added the trailer hitch for the bike trailer, I made sure that all the lights were waterproof and supplied by common rechargable batteries, I switched out the gear stacks with higher quality components, and I carry CO2 cartridges, spare inner tubes, and tools in various pouches on the bike.
I lived a bicycle lifestyle for many years . . . and I saved huge amounts of money, I was healthier and more energetic, and so on.
If you see below, this is very similar to my bike trailer:

I have used it to carry groceries, clothing, school materials (for my nursing program), and even to bring my cat to the vet.
