menu.py: TypeError: unsupported format string passed to NoneType.__format__

[ldrolez]

With the git version, menu.py starts displaying data, and then encounters an error:

...
...
Driver Seat Heater: 0                  Passenger Seat Heater: 0
Is Front Defroster On: False           Is Rear Defroster On: False

TypeError: unsupported format string passed to NoneType.__format__

$ python3 --version
Python 3.7.3

That would mean that either ve['vehicle_name'] or ve['odometer'] equals to None, which is unexpected.
Can you add this line before line 61 and share the output:
print(ve['vehicle_name'], ve['odometer'])

[ldrolez]

Yes I never tried to change the name of the car
