I do not find it so easy to accidentally run into UB in C if you follow some basic rules. The exceptions are null pointer dereferences, out-of-bounds accesses for arrays, and signed overflow, all those can be turned into run-time traps. The rules include no pointer arithmetic, no type casts, and having some ownership strategy. None of those is difficult to implement and where exceptions are made, one should treat it carefully similar to using "unsafe" in Rust.
