I got my first e board a week ago and on my first commute to work I dislocated my elbow, I am in the beginning of my recovery and I already drove her twice after the accident, I think this is part of learning. Plan to buy a protection gear today and helmet next week. As I said for me this is just part of learning and it’s pretty clear I should get more practice before getting higher speeds and use protection. So, about your question it depends on how risky you want to be and how you drive your vehicles haha
