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
a) Supernova: youtube.com/watch?v=RN_aGFhcnPo; review
b) Lupine 1) youtube.com/watch?v=bOCvVHNaZkw&t=4m25s 2) youtube.com/watch?v=LVVm4UTlkjg&t=2m00s 3) youtube.com/watch?v=sv0GLx7Z07A&t=13m25s
c) B&M Ixon Space youtube.com/watch?v=Uhv7WXj5xpA&t28m20s (dipped a bit low), beamshot on a MUP (optimum adjustment)
d) Outbound Lightning focal road (non StVZO certified but with suitable optics) youtube.com/watch?v=8hnms2k7Ti0
