Driving under the influence of alcohol is a serious violation that endangers traffic safety. To ensure traffic safety, according to relevant national regulations, a driver with an alcohol content of $20\sim 79mg$ in $100mL$ of blood is considered to be driving under the influence, while $80mg$ and above is considered drunk driving. Suppose a driver consumes a certain amount of alcohol, causing the alcohol content in their blood to rise to $1mg/mL$. If after stopping drinking, the alcohol content in their blood decreases at a rate of $30\%$ per hour, then they will need at least ______ hours before they can drive. (Note: If less than $1$ hour is required, it should be counted as $1$ hour. For example, if the calculated result is $7.3$, the answer should be $8$ hours.)<br/>Reference data: $\lg 0.2=-0.699$, $\lg 0.3=-0.523$, $\lg 0.6=-0.229$, $\lg 0.7=-0.155$.
