If you really hate helmets, you could use one of these instead: https://hovding.com/
Here in the Netherlands, biking (without support) at speeds around 15km/h if you are in good health and of sound mind, is not more dangerous than walking or traveling by some other means. Recently, the number of traffic causalities has gone up, that those are mostly related to the use of e-bikes by elderly people and younger people. I feel that if you need support for biking when you do not have the strength (due to old age), you probably are not fit for biking at all. Many young people using e-bikes remove the speed restriction allowing them to bike at speed up to 30 km/h. At those speeds, the chance of accidents go up very quickly.
But if someone will wear one of these things who wouldn't otherwise wear anything at all...
Cycle routes in the Netherlands are awesome! Things are slowly improving here, but we're still a long way from that level of care placed into the design.
