Obviously flustered, this guy blurted out "all you really need is one top quality kit."
It only makes sense to have kits which are geared towards the situations you would likely encounter stored in the most appropriate location.
I'm betting this person has jumper cables in his car, and bandaids in his medicine cabinet, while not very extensive kits -- they serve the same purpose and could arguably be considered as such.
I happen to have...
PSK
EDC Bag
FAK (generally kept in EDC bag)
Trunk Kit (Car Maintenance/ Emergency stuff)
Glove Compartment Kit (Passenger Maintenance)
BOB/ Travel kit
