>>> sorted('Do you even kata?'.split(' '))
['Do', 'even', 'kata?', 'you']

1
123
12345
2
234
3
...

Check your units

Notice that [x,y] coordinates are described with units of 100m

Prior to the "Go straight on for 900m" you were at an intersection...

So you cannot have been at [0,-1] because that represents [0,-100m] and the city blocks are 1km across
