There are now so many changes in speed limits on most A roads in

Round here they've downgraded the dual-carriageway bypass from 70 (for
cars) to 50, but left the adjoining single carriageway at as 60. So
you're stuck behind a lorry, reach a dual carriageway stretch and then
(theoretically) still can't overtake. Still not as bad as
Nottinghamshire where they've reduced dual carriageway bypasses to 50
(or 40) with average cameras.
