Double check for yourself but this seems to be the situation:

"Private vehicles

You don’t need to self-isolate if you travel through a non-exempt country, territory or region and you don’t stop there.


If you do make a stop, you don’t need to self-isolate if:


    no new people get into the vehicle

    no-one in the vehicle gets out, mixes with other people, and gets in again


You do need to self-isolate if you make a stop and:


    new people get into the vehicle, or

    someone gets out of the vehicle, mixes with other people and gets in again"

So it sounds like you can get out of your vehicle if you don't mix with other people which presumably means maintaining social distancing. That probably means sleeping in your vehicle. Presumably you would be questioned and you would have to convince them about how you avoided mixing with other people when you bought food or used the toilets and where you slept.

If you arrive in the UK this week, you'll need to quarantine for 14 days.  After that, who knows?  Our government seems to be making it up as they go along.

Yes, you'll need to quarantine in the UK for 14 days.

You might not be driving to any of these! Have you checked EACH countries current travel restrictions, covid testing requirements, quarantine/isolation requirements? You could get stuck having to self-isolate at your expense for 14 days or more in each one! You are not thinking, not doing your research, not preparing properly. Stay HOME!
