Personal choices play a key role in advancing legislative change and facilitating effective enforcement. Legislation and enforcement only played a partial role in reducing the rate of driving while intoxicated. DWI was still normal and socially acceptable for decades after we started banning it. We changed our attitudes, we stigmatized the behaviour, we created new norms, we invented the concept of the "designated dr…
I strongly disagree with the attribution of drunk driving reductions to the culture. The culture is a byproduct of how significant the punishment has become, which is what really led to the reduction. Back in the 70s getting pulled over drunk was punished like running a red light (i.e. a nominal fine). The punishments were ratcheted up to now where a DUI results in a 10k fine in some states and an immediate license s…
In the UK, the standard penalty for drink-driving has been the same since the early 70s - a 12 month driving ban and a modest fine for the first offence, a three year ban for a second offence and a possible prison sentence of up to 6 months for further repeat offences.
The penalties haven't changed in years, but the rate of drink driving has fallen drastically. What has changed is the culture. Persistent campaigning from both government and grassroots organisations has made drink driving completely unacceptable. Today, it would be considered perfectly reasonable - perhaps even admirable - to call the police on your own friend if you know that they're drink driving. There's now far less proactive enforcement of drink driving laws, because it's not a common enough offence to warrant random testing and the police expect to get tip-offs from the public. It's seen as a foolish and selfish thing to do, a marker of personal weakness, a sign that you're some kind of alcoholic.
