Ask Brits who their MEPs are, see if they know (or have even heard of MEPs... modulo Farage for his infamy)
Not rly an MEP problem I think. Most people don’t care that much.
People are constantly overwhelmed with choices, and eventually they start to economize on their decision-making to focus on immediate needs. Certain systems (particularly those designed by marketers and politicians) are set up to take advantage of this trait.
