I can't promise anything, of course, only share my dad's experiences. He's consistently found drivers to be helpful (with some direction--you'll need to tell them how it all works). One thing you could do if you're concerned is use Uber/Lyft exclusively. They have the option to message your driver, so once you get someone assigned you could message them and make sure they can help with the
ECV. If someone didn't want to for some reason, you could cancel and get a different driver right then, rather than waiting till they showed up.
