Engine braking != regenerative braking.
I used to drive a Prius - interesting car, not really eco-friendly (due to the environmental cost of manufacture) but one of those which (IMO) gave a boost to getting some of the same technology in mainstream engine driven cars. Whenever I took my foot off the throttle or eased up to maintain speed on a downhill, it would be recharging the battery. Light braking apparently took some of the energy from the wheels to assist battery recharging (heavier braking used brake pad friction as normal). This was with the gear selector in F for Forward (or was it D for drive - I forget now).
Anyway, the gear selector had Neutral, Foreward (or Drive), Reverse and 'B' for 'Braking' - which did not disconnect the clutch when not accelerating; i.e. in all other conditions, no accelerator pressure = no clutch engagement, engine disconnected from wheels (and stopped usually). In 'B' the car slowed substantially more quickly than otherwise - about as quickly as a modern auto in Drive. Regenerative braking was not increased though, simply the engine compression was being used to add to the friction in bearings etc which was slowing the car = engine braking.
In modern driving practice, using engine braking to slow for a hazard is discouraged: Modern brakes are phenominally better than 20 - 30 years ago and don't need the assistance, clutches are not designed as braking surfaces (and using engine braking without rev matching each change does exactly that). Gas to go and brakes to slow is a reasonable summation;
but (a big but) use of engine compression to
control downhill speed is still encouraged. Modern cars tend to have lighter rotating parts than older ones (better engineering and computer controlled fuel flow combine with this to improve both mpg and emissions), which means they cannot provide the same control at the same gear ratios, so a lower gear needs to be selected - with appropriate rev matching to prevent premature clutch wear.
As regards the OP - I don't know the road and cannot tell if the cyclists were being overly selfish, or whether it was simply a selfish driver expecting them to dive out of the way as soon as he is on the scene. By the driver's own description though, he definitely needs remedial lessons in car control
Slipping the clutch to stay behind
Clutch fully engaged and control speed if necessary (I doubt it would be necessary uphill) using footbrake. Any modern car easily travels below walking speed with the clutch engaged; if yours can't then stop (as others have said) in one of those passing places and let the council vehicle behind you past (the driver of which is presumably coping adequately with the slow speed up a steep hill).
Plenty of steep single tracks in Wales, I remember plenty in Hampshire; in both places the usual cause for driving slowly was some farmwork. Anyone unable to keep his car below walking speed without burning the clutch out simply should not be on the road.
