The money raised by Proposition B will unlikely go to improving the roads.
Step-by-step explanation:
Proposition B was a tax system in Missouri that would increase the tax amount for the government. The money collected by Proposition B will likely go to improving roads in Missouri.
Firstly, half of the people didn't know to drive. And the tax would be paid even by people all people who don't know how to drive. Rohrbach mentioned that already a huge amount of tax getting paid to the government.
And that money went as airplane tickets for commissioners to their committee meetings. If they wanted to improve the road they might have done it already. They won't bring a new tax system that increases the tax amount.
