C++ and C are no longer used for the same types of projects so C++ is not a better C.
All kinds of major projects switched to C++ already, for example GCC. All the major new projects, for example LLVM, are also in C++ from the get-go.
Even the Linux kernel is considering switching to C++ now.
Source?
considering doesn't mean it will happen in near future, because toolchains/ecosystem is not there, the same is applicable for many other projects.
Thankfully the Linux kernel development relies on testing instead.
