To expand the scope here a little, personal electric transport will take over city centres over the next five to fifteen years and managing that transition will be tricky and divisive.<p>The fundamental driving force of this change is that electric vehicles scale much better than fossil fuel power vehicles. A 500watt ebike is perfectly quiet, clean and reliable whereas a gas engine of similar power and weight is messy, polluting and loud.<p>Start with bike paths.  In North America, the standard is becoming 20mph&#x2F;32kph.  I ride an ebike often and I find this is more than fast enough and probably equal to about an automobile&#x27;s 40mph with traffic lights.<p>Vehicles allowed on these paths should have a limited width and the allowed speed should depend upon its weight.  It&#x27;s not necessary to restrict motor power since speed is regulated by weight.  So yes, if you&#x27;re on a pedal bike you still have to follow the speed limits even if it&#x27;s down hill.  Some jurisdictions already follow this scheme with police and speed guns (Calgary is one as I recall).<p>The next step is to transition fossil fuel traffic to electric traffic in the city core.  The most effective approach here is to initially allocate an entire lane on say, every fourth road, to electric (but not pedal only), vehicles of all sorts.  The reason for excluding pedal only, ie normal bikes, is that their acceleration is too slow when starting from a dead stop at intersections.  Whereas electric bikes have excellent acceleration, even better than cars from a dead stop.<p>Allocating a full lane to electric traffic (even Teslas) will be a big incentive for commuters to switch to electric transport.  Another benefit is that it&#x27;s much cheaper to do it this way than to create bespoke bike lanes.  Just the low concrete dividers on top of the lane lines is enough and they can be laid down or removed very easily and cheaply for flexibility.  As more commuters adopt electric transport more lanes can be allocated to them.  Before you know it the city core will be all electric excepting delivery trucks.
