ebikes are vehicles in the same way that motorcycles are as in they are not exclusively human powered. They belong in the normal lanes with the other non human powered vehicles. It’s dangerous to riders in the bike lane legally when ebikes and other vehicles are whipping around because they want to skip the line. According to NYC law you are only allowed 750 watts max and 15mph limit to use the bike lane. They really need to revisit that because these are not safe to others in the lane.

bows thank you thank you. Glad about my efforts being well received, and even more so it got you out of bed! Cheers and may your day remain on the up.

Actually, after kinematic analysis of the required fingertip trajectories upheaves both of these arguments. If you calculate the aggregate spatial displacement across a standard 2D Euclidean plane for both input strings, the former macro sequence yields a significantly lower metric footprint than the latter.

For the sake of empirical demonstration, we can map this across a standard ANSI 100% layout using a normalized key pitch constraint where 1 U = 19.05 mm. By establishing a Home Row Idle-State Matrix as our behavioral anchor and tracking independent multi-finger vectors using the standard Pythagorean metric tensor—calculating the straight-line distance d = sqrt( delta_x^2 + delta_y^2 ) between consecutive keystroke coordinates—we arrive at the following quantitative breakdown:

Macro Sequence 1: sudo [shift] !! [enter]

• Single-Handed Vector String: 40.878 U
  • Net Linear Displacement: 778.7 mm
• Dual-Handed Touch-Typing Matrix: 8.424 U
  • Net Linear Displacement: 160.5 mm

Macro Sequence 2: [up] [home] sudo [space] [enter]

• Single-Handed Vector String: 40.989 U
  • Net Linear Displacement: 780.8 mm
• Dual-Handed Touch-Typing Matrix: 21.728 U
  • Net Linear Displacement: 413.9 mm

tl;dr

Fewer keystrokes != less work. Even though typing !! looks like more work, it isn’t because your finger travel distance is significantly shorter when executing those keys using two-handed touch typing on a standard ANSI QWERTY keyboard.

I have a friend who is getting this type of therapy soon! Really cool stuff, but hope none of us have to go through it.
