ᐅ Driveway too steep? Height difference between garage driveway and street

Hello everyone,

I am currently planning my house. It is located on a street with a slight slope.
The plot has a length of 18.5 meters (61 feet) facing the street, with an elevation difference from the highest to the lowest point of 0.92 meters (3 feet).
The entrance of the house would be 8 cm (3 inches) above street level. A gutter is being installed in front of the entrance as a precaution.

Now to the main issue:
The double garage is placed next to the house for "sunlight reasons." I am concerned that the driveway, as it is currently designed (see attachment), might be too steep. The garage door is 5 meters (16 feet) wide. The architect has currently planned the following height differences (from the garage driveway to the street):

Left side outer edge: 0.5 meters (1.6 feet) height difference at 6 meters (20 feet) distance to the street → 8.33% or 4.76 degrees slope
Middle: 0.35 meters (1.1 feet) height difference at 5.8 meters (19 feet) distance → 6.03% or 3.45 degrees slope
Right side: 0.2 meters (8 inches) height difference at 5.5 meters (18 feet) distance → 3.63% or 2.08 degrees slope

What do you think? Am I worrying unnecessarily? Do you have any suggestions for improvement?
