Opinions are like bumholes - everybody has one
The fact of the matter is, using the hand brake was drilled into people learning to drive in my era. It was as much used as an indicator to the examiner that you acknowledged the red light OR the rare case of a Stop Sign (most such signs in the UK are ‘give way’) as anything else
Brake lights are very bright - if you’re stuck in a line of queueing traffic, it’s very uncomfortable to the eyes - and I’m courteous enough to want to do something about this for the poor person following
Again ‘in the old days’ having worked on quite a few of my own and cars belonging to friends, you often saw the 21W brake light bulbs melting or distorting their holder - demonstrating they were not designed for semi continuous use
As for stop/start systems on manual transmission vehicles - the only ones I’ve ever used have relied on depression of the clutch pedal to restart the engine. Thankfully those days are long gone
Enjoy your Sunday, everyone
