On a side note, it is still legal to use a CB isn't it.?
What's the difference.?
Isn't CBs they heyday of the 1970's and 1980's or something like that? As a kid, I used to watch US movies and television shows where you would see characters using CBs, even thought you are using one hand to hold the mic, you're not fully in control, but surely in those days, we all weren't very much into health and safey? You would only need a hardhat if working on a building site, and that's all. For a F1 racing driver, just overalls and leather helmet during the 1950s. etc., etc.,
Nowadays, we're more and more worried about health and safey, at a building site, it's more and more kit, not just the hardhat, but it's extras, like goggles, gloves, hi-vis vests, etc., for F1, it's now layers and layers of fireproof clothes, full helmet, that even includes this kit at the back lock it to the car, etc., etc., and no use of mobile phones, both hands on the wheel and focus!
Everything changes over time.
Assuming if say mobile phones did not happen, and in today's modern age, if we were still using CBs like the 1970s, I would guess it is likey that the law would changed and that CBs would be illegal today.
On a side note, assuming if technology advanced very fast and we have those modern-day mobile phones in the 1970's, chances are nobody would have thought of making using them while driving illegal. If we had something like iPhone in the 1970s, we would have been using them freely while driving.
The difference is time, over time laws have changed, even if some laws slipped through and didn't get a chance to be updated. CBs in 1970s fine, mobile phone in 2010s illegal, for all you know, it could have been mobile phones in the 1970s fine or CBs in teh 2010s illegal.
That's just my view, that the different is time.
