Then you live in a different world than i do. Any conical beam pattern lamp will blind motorists. Of course a motorist will not blind you, because cars and (motor)bikes are forced by law to have passing beams with a cut-off:
1) US based automotive lightning regulations:
FMVSS 108, (you'd have to search the text for the actual requirements, i don't know where that is written)
2) UN ECE automotive lighting regulations:
UN ECE R149 (on page 31 of the pdf you find requirements for a passing beam, and page 78 you find the measurement screen)

Contrary to you, I have tested all current high powered StVZO lights available on the market, and these a more than adequat for road riding. I do as well have typical "round beam shape" lights, they do more harm than good on a road, especially with oncoming traffic. You obviously haven't ever tried modern high powered StVZO lights.
Here's a bunch of exemplary (video)links for StVZO (or UN ECE R113) certified lights. Keep in mind that video/camera shots never really give justice to any lights, they are perceived even better in reality
