Dear Ken san,
Good day,
Nice to see you again
Thank you for your comment.
First, let I explain more detail about Q1.
As you know, system calculates the car parking position based on the length of model.
In case of wrong model dimension, system couldn’t calculate the car parking position, so that’s why car couldn’t be parked in user’s defined location.
Second, I totally agree with you that system should do some validation to verify inputting data from user.
Actually, we are discussing internally to fix this issue.
And my email just want to notice how to overcome this error if it happens again temporarily, until we find the solution.
We will give you the updating information about it soon.
If you have any request, please feel free to contact with us.
