* Update max_lat_accel.py
The error you're encountering is due to the fact that the code is trying to calculate the 90th percentile of lateral acceleration values that are less than 0, but there are no such values in the dataset. This results in an empty list, which causes the np.percentile function to fail with an IndexError
* fix
* simpler
