The motorway is fine, so long as you don't keep the car under light load at constant revs. So you will have to constantly accelerate and then slow down, which is possible, but difficult to do.

Not labouring is always important, but it was one of the key objectives in the old days when bearing surfaces had to be run in. Modern bearing surfaces are so good from new, that the primary objective is now the piston rings.

Every racing engine I have built has been run in this way too, and has worked well.

Most owners, if they glaze their bores a little, will never know. They will just have to top up with more oil and live with a little less power.
