Not really much need of any manual intervention if you've the electronic handbrake with hold assist as the brakes are automatically applied when the car stops, then the handbrake automatically applies if you turn off the engine, or remove the seat belt or open the drivers door. The handbrake will also automatically disengage when you pull away but only if the seat belt is on. The only time I ever use the handbrake manually is if I don't want to dazzle the person behind me at nightime as hold assist puts on the brake lights. I also have been driving using conventional handbrakes for 45 years but I've got used to mine, now when I get into my partner's fiesta I find it a pain to have to use a mechanical handbrake...
The way the hold assist keeps the brake lights on is the most brain-dead feature ever. It's bad enough when morons sit at lights at night with their foot on the pedal and their LED brake lights blinding the poor sap behind without this feature promoting it!
The electro-mechanical handbrake is actually a step in the right direction as its ease-of-use promotes using it instead of the foot brake and thus less dazzling, only for everyone with the hold assist option to never use the handbrake at all and instead dazzle all the time
