One thing you may discover with e-bikes is that at the higher speeds (35Kms+), car drivers tend to underestimate your speed. Also some cycleways are narrow and have blind corners and if you come up on someone doing 30km the other way then your combined speed is 60km! I'm a roadie and if i'm chugging along at 40km-ish I find a lot of cars turn in front of me because they have no idea how fast you can go.
