I don't like riding in traffic mostly because drivers tend to have a short fuse for anything that isn't exactly at the limit, but on bike paths everything works just fine. The problem is that s-pedelecs are technically lumped in with the scooters, even though there is no throttle and there is absolutely no way you are going to sustain 40 Kph+ for anything but a very short period. But they're still pretty new and little by little municipalities are adapting and allowing s-pedelecs to use the bike lanes. What helps is that s-pedelec riders are extremely defensive. In town I simply reduce the assist to 'eco' and cycle with the rest of the bikes, and on the intercity bike paths I go as fast I conditions allow, typically 35 to 38 or so. On a longer trip that averages out to 33 to 35 Kph, which means a 1 hour car trip turns into a 2 hour bike trip, which is acceptable (and never traffic jams, which can turn that 1 hour car trip into a three hour car trip!).
