If I get an e-bike, should I also consider buying body armor meant for motorcyclists?

I live in an area where there's so many crazy drivers, that even with my helmet and pads (knee, elbow, wrist), I still don't quite feel safe. I'd go for armor that protects the chest, abdomen, back, and shoulders. Extending to the limbs are great, but it'll be too expensive and not practical during the spring and summer.
