Difficult, but not impossible
A few years ago we visited Chile
At one point we were in Vina Del Mar and wanted to go see the penguins in Temuco
We got on route 5 and the GPS said "in 400 miles, turn left" and we only got to see a lil of it
If wr had started at the peruvian border, we could have done over 2000 miles
Which is funny, cause at its widest point, the country is barely 200 miles wide
