The road network around Brussels works well. You can move between districts fast, with few delays. Drive from Ixelles to Uccle, park close to Grand Place, or take a turn down the inner ring.
Outside the city, head south to Waterloo in under 30 minutes. Go east to Leuven and stay on clear, flat roads the whole way. Mechelen is just north and connects directly to the ring without tight corners or stops.
Main routes like the E40 and E411 keep traffic steady. You’ll cruise through most of Belgium without a problem.
