TMG, tolls are just another form of a tax. We can't avoid them. I have yet to see a "tax" discontinued after it's intended purpose was satisfied. The government always seems to find another purpose for the income. Around here, they have been talking about highway tolls to pay for new road repairs----that's what I thought our current road use taxes were for--- what was I thinking, silly me :hehehe.
Yes, your tolls probably did pay for your bridges, and they are also supposed to pay for upgrades and replacements, and the salaries of the toll booth staff........ so if they reduce toll staff to only a self pay system, do you really think they will reduce the $ you pay, oh heck no.... I do agree with you though, if it is going to be a 'requirement' to pay no matter what, then yea, make it as easy as possible. They wouldn't have to have all booths manned. I have ridden out there. Visited a friend in Manhattan then we went to New Hampshire and yes the toll booths were a pain.
Unions have a place, but they are like the government, they got to greedy for their own good and have contributed to their own downfall and demise.
