Default Mitigating Driveway approach/depart angles

Just moved into a new house. The driveway breaks uphill from the street at pretty sharp angles in two places: at the curb, and where it departs from the sidewalk. Photos below.

My wife's minivan has long overhangs and a low-hanging hitch receiver and can't get in at all. Even my Model S scrapes sometimes.

Anybody have experience with something like Bridjit or another recommendation for how to address this? I'm hoping not to take on the cost of a new driveway anytime soon.

Ouch, that looks like a tough layout.

Do you go in/out at an angle? That is needed for mine. I'm talking sharp, like you are almost trying to parallel park right next to your curb-cut angles.

If where you live allows you can use one of these where the curb hits the street:

Growing up we used a 2x12, that last option looks a little more modern

X2. That does not look good, especially since you likely wouldn't want to block the sidewalk. May need a combo of adding something and driving sideways. Or a lift kit for the minivan (may need to check handicap conversion suppliers for that)

I should mention there's another variable in this equation: A moderately strict HOA...

A model S with a lift kit and light bar would be unique..

Driveway replacement not needed, but you may be able to replace the apron (or ask the County, state, etc. if they happen to own it). Go back a sidewalk panel or two on each side and slope them down, and have the upper part of the apron be more in line with the driveway above.

You can't really do anything at the curb line because it will screw up the drainage.
Maybe a 2x, etc., but chances are it will not last long, as someone will drag it away and toss it.

You could also have the driveway ground down some, but that doesn't look too good (exposed aggregate), and it still does not fix the issue at the curb.

+1 what David said.
Question though...is the problem area the curb of where the sidewalk meets your driveway?

If it's the issue is the sidewalk/driveway you may have to eat it and redo the angle of the driveway. You should see my crazy slope, redoing the apron helped a lot, without it my daily drivers wouldn't even stand a chance. Luckily the 914 has low overhangs, but the 356 sport exhaust scrapes if I don't take the perfect angle-in (I'll have to swap for a through-the-bumper exhaust in the future)
