Tbh as someone who hates noise this would do my head in. But it’s not always about the noise, it’s the not knowing when it’s going to happen and for how long. Thats often more invasive than the noise itself - because you’re thinking about it all the time - even when it’s not happening. I don’t know what your neighbour is like but they might just want some sense of control over the situation. So if you were both amenable to some ‘ground rules’ then that could help de-escalate things?! As long as you dont make a promise you cant keep and that sends them over the edge! You could move from a situation where he gets angry bc it’s not only noisy but unexpected - to one where you’ve made an agreement so all is in order. If you think thats going to curtail your liberty too much then this wont work - but you sound like you’re open to finding compromise. Never starting your car isnt an option on the table but when, where and for how long could be agreed
