Welcome to my list of reccomendations, items that might help with your driving journey.
Blind Spot Mirrors
These can be applied on your door mirrors (wing mirrors). They usually help with bay parking, or the intended use of blind spot helpers
Tyre Inflators
Useful for when you have a puncture/flat tyre.
Official DVSA Guide to Driving
I do recommend this book, it gives you reasons why you do things or why things are.
Dash Cam
Can be useful in the case of an accident- you can prove to the insurance you were NOT at fault!
