I used to do a long daily commute, here are my top tips
Buy breakdown, recovery car insurance with AA or RAC
Never let your petrol level get below half full, before starting a long journey. Because if there is an accident, you will be delayed for several hours & you will need extra petrol
Keep drinks & snacks in the car (incase of delays)
Keep water in the car topped up to use on the windscreen
Keep waterproof jacket in the car (incase of delays)
I also carry a fluorescent jacket & a first aid kit
If there are road closures you need to be able to get off your normal route & navigate to your destination via alternate routes
A 2 hour journey will turn into a 3,4,5,6+++hour journey if there are accidents, road works, bad weather, unexpected events
Basically, you just get used to spending hours in the car & stay alert
Good luck
