The concept of an "endless road" in the context of the universe is a bit abstract since the universe itself is not known to have an edge or boundary that we can reach by traveling in any direction. According to current scientific understanding, the universe is thought to be infinite or at least extremely large.
If we assume that you could travel at the speed of light, which is the fastest speed possible according to our current understanding of physics, and you kept driving continuously, you would still not reach the end of the universe. This is because the universe is expanding, and as you move through space, the fabric of space itself would continue to expand, pushing the boundaries of the observable universe farther away from you.
To put it simply, the universe is constantly growing, and it is not confined to any finite volume that you could reach by driving. So, in practical terms, you would not be able to reach the end of the universe by driving on any road, no matter how far you go.
It's important to note that our understanding of the universe is constantly evolving as scientists make new discoveries and advancements in cosmology. So, while our current knowledge suggests an infinite or extremely large universe, future discoveries may provide us with new insights that could change our understanding.
